2. Outline Scope of installation/integration effort. Plans in EHN1 for installation area. Installation process. Conclusions. 23-Feb-2016Jack Fowler | SP PD Installation discussion2

3. Installation and integration scope Review all activities with CERN HSE DSO for proper training, access and PPE requirements. Also develop work packages. Set up receiving and testing area for components at CERN.  From each subsystems QA plan, develop the test areas required at CERN. Organize effort for integrated testing at CERN before, during and after installation. Organize infrastructure required in EHN1. Organize detector survey during construction. Set up tooling required for installation in EHN1. Coordinate detector installation with cryogenic installation. Install and test the detector components. Commission detector. 23-Feb-2016Jack Fowler | SP PD Installation discussion3

4. Clean room requirements and test equipment needed Currently the clean room is specified as a class 100k or ISO 8 (grey room). Must have an entrance SAS for personnel and a pass through for the TPC components. Light filters to limit UV exposure (< 450 nm) of photon detectors. Test equipment for TPC components.  Electronics racks with test equipment (TBD, some fraction of DAQ equipment).  Cold test (likely N2 gas) and shielded Faraday cage for testing integrated APAs.  Cold feed thru flange and cold cables for CE and PD.  Tension meter for spot checks of APA wires.  Small electronics equipment (DVM, resistance measurement device, HV supplies). Overhead hoists for lifting TPC components (estimated capacity 1000 kg). 23-Feb-2016Jack Fowler | SP PD Installation discussion4

8. Clean space in EHN1 23-Feb-2016Jack Fowler | SP PD Installation discussion8 APA rotation and integration of CE CPA, FC, ground plane integration area (~4 x 8.5 m) (also access through CR roof of EHN1 bridge crane). Leaving this space available allows for APA integration and installation inside the cryostat to happen in parallel. Integrated cold test box (could be cabled to full chain electronics on top of cryostat) Integrate PD SAS comments Not ideal location for material flow. Probably too small for moving long materials inside. Need to understand what space is available. Do we need to extend the material entry into the clean space. Could complicate the PD integration area. Could we design a vertical material SAS over in the crane coverage area? Scaffolding is shown for access, however, mechanical lifts could be used as well.

9. Discussion of clean room in EHN1 Very convenient location. Minimizes packing, unpacking and transport of TPC components to be tested. Set up only one area. Eliminates the need for a second clean room at another place at CERN. Eliminates the need for another “DAQ/test stand” at CERN. Gives the possibility of utilizing the final read out chain. A vertical test stand (cold test with gaseous N2, Faraday cage/shielded) inline with cable feed thru may be a challenge. The current concept is a “drive thru” version. Clean room can stay in place. Confirm the ability to install CE and PD in vertical orientation. We need to understand the space required for assembling the FC and CPA and the complete TPC testing plans for all components at CERN. We need to understand the access possibilities during H2 beam commissioning, H4 beam commissioning, potentially LAr filling of 2 phase ProtoDUNE, conflicts with cryo construction/testing and other EHN1 activities. 23-Feb-2016Jack Fowler | SP PD Installation discussion9

10. Cryostat space 23-Feb-2016Jack Fowler | SP PD Installation discussion10 APA row Jura 3.6 and 2.5 m drifts CPA row APA row Seleve 3.6 and 2.5 m drifts Temporary Installation Rail All rows will be installed here.

11. APA / CPA installation concept 13-Jan-2016Jack Fowler | Installation/Integration WG11 Temporary access platforms will be constructed inside the cryostat for access to the detector as needed. The APAs (and CPAs) will be installed vertically through the TCO via an extension rail. TPC support (X) rails Translation (Y) rails When APA #1 has been integrated and tested with CE and PD it will be moved on X rail inside cryostat and cabled to cold feed thru for full chain testing. When APA #2 arrives integration and testing can begin independent of APA #1 outside of cryostat.

12. Translation of complete rows of APAs /CPAs to be translated 13-Jan-2016Jack Fowler | Installation/Integration WG12 After a full row of components have been installed on their rail, the entire row will be translated to its nominal positon. Access platforms will be relocated as needed.

13. Installation sequence #1 23-Feb-2016Jack Fowler | SP PD Installation discussion13 1 st row of APAs are installed and cabled as they are available. Testing of full electronics chain can begin. The cables will be connected to Seleve FTs. Install position is an additional 1.2 m away from the current Seleve FT position in Y direction. Cable lengths may be adjusted or a set of jumper cables used to make the connections to being testing.

14. Installation sequence #2 23-Feb-2016Jack Fowler | SP PD Installation discussion14 After full row is complete, the APAs will be un-cabled and translated to the Jura position and cabled to Jura FT for continued testing. New rail will be moved into the “install position.” The installation of the CPAs can begin.

15. Installation sequence #3 23-Feb-2016Jack Fowler | SP PD Installation discussion15 After the CPA row is complete, it will be translated to the nominal position. Work can now begin on the installation of the Jura side FC. This order of installation is done to allow more time for APAs 4, 5 and 6 to be integrated and tested outside of the cryostat.

16. Installation sequence #4 23-Feb-2016Jack Fowler | SP PD Installation discussion16 The beam side end wall FC will be installed.

17. Installation sequence #5 23-Feb-2016Jack Fowler | SP PD Installation discussion17 The 3 upper field cage panels will be installed. Note: Access to the CE on APAs 1, 2 and 3 is now not possible.

18. Installation sequence #6 23-Feb-2016Jack Fowler | SP PD Installation discussion18 Completion of the Jura FC as follows: Install the upper half of the north FC wall. Disassemble scaffolding in this drift area. Install the lower FC panels from beam side to N side. Removal of floor protective panels will be completed and the areas are covered with the FC panels. Install the lower half of the north FC wall from the outside of drift volume. HV can be installed at this point. Need to evaluate the optimal time for this.

19. Installation sequence #7 23-Feb-2016Jack Fowler | SP PD Installation discussion19 New rail will be moved into the “install position.” APAs 4, 5 and 6 will be installed and cabled to the Seleve FTs.

20. Installation sequence #8 23-Feb-2016Jack Fowler | SP PD Installation discussion20 When APA row is complete, it will be translated to the nominal position on the Seleve side of the cryostat. It is likely that the APAs will need to be un-cabled and re-cabled during this move.

21. Installation sequence #9 23-Feb-2016Jack Fowler | SP PD Installation discussion21 The upper half of the north Seleve end wall FC will be installed. The upper two FC panels may be installed at this point. This will block access to the CE for two of the APAs. After this is complete, all of the remaining FC panels must be moved and stored inside the cryostat for the closing of the TCO. Also all of the materials for closing the TCO must be in the cryostat prior before beginning the closure. Is there enough storage and work space available?

22. Installation sequence #10 23-Feb-2016Jack Fowler | SP PD Installation discussion22 After the TCO is closed, the beam side Seleve FC will be installed. Then the final upper FC will be installed. The scaffolding from the Seleve side drift can be removed. After the TCO is closed, access to the cryostat will only be possible through the manholes. All materials not in the cryostat must fit through the manhole. All tooling inside the cryostat can only be removed through the manhole.

23. Installation sequence #11 23-Feb-2016Jack Fowler | SP PD Installation discussion23 The lower FC panels will be installed from the beam side towards the north. The floor protection will be removed as this progresses. This may also be an appropriate time to complete the installation of the floor cryo piping. The lower half of the remaining FC end wall will be installed. The TPC installation will be complete.

24. Conclusions 23-Feb-2016Jack Fowler | SP PD Installation discussion24 Developed a conceptual layout to perform most (all) of the integration/installation of the TPC components in pit B of EHN1. We need to understand all of the various schedule implications. The full list of QA tests and requirements needs to be completed to understand if all work can be done in EHN1 or is another test area needed at CERN. Installation sequence allows the earliest testing of APA #1 with final full electronics chain. Completion of the Jura side FC provides additional time for integration/testing/delivery of APAs 4, 5 and 6.

30. Modular Electronics Enclosure Concept These enclosures could make bubble collection in the lower APAs more manageable. ProtoDUNE Cryostat Design Review Dec 17-18, 201530 This concept is developed to allow access to both sides of the readout electronics from one side of the TPC

31. 13-Jan-2016 Jack Fowler | Installation/Integration WG 31 Overview of TPC support system Crossing (support) tubes AP A rail CP A rail APA rail Beam window side Fixed point X Y Y beam X beam Flange on cryostat Support tube APA trolley Installation: 1.Install the 6 support tubes above the APA rail. 2.Lift the y beams through the center penetration and secure the beams at the ends. 3.Install remaining tubes and connect beams at midpoint. 4.Rig the x beams from the y beams and mount them. Roller mounted beams and slotted holes between support tube and y beam allow for relaxed tolerances on the penetration locations. Dan Wenman

32. 13-Jan-2016 Jack Fowler | Installation/Integration WG 32 x y “Compressed” view of support Y beams are fixed at the midpoint in x, y, and z and allowed to contract towards y = 0. X beams are constrained on the beam window side to minimize moment with respect to the beam window. X beams are free to roll in y for installation After installation, the middle x beam is locked to the y beam. As the Field cage shrinks, the outer 2 x- beams are pulled to the center. APA trolleys closest to the beam window will be constrained after installation. Bearings in the rollers will be in the ullage and will be lubricated with Teflon cages or WS2 coatings. Will be tested for contaminants. Beam window side Fixed point Trolley stops x6 not shown Dan Wenman
