4. Back-End Electronics for HF
Replacement of VME based system with uTCA for HF scheduled this year – also support lumi measurement
Our system should be compatible with the present as well as the new front-end electronics system.
June 24, 2014 4

5. Major Milestones Had a PRR (Feb.) & ESR (June) reviews in 2013.
Review in January 2014 – mini review
Working on feedback from HCAL readiness review in May
Weekly meetings with HCAL management.
June 24, 2014

6. Status of Commercial Items
MCH card
Power module –
Crate – Vadatech VT892 – 7 of 11 ordered shipped
For HF items delivered and tested.
AMC load card from Samway for testing and burning of Vadatech crates., some spares.
Potential bulk power supply – Power one (Aspiro)
3 Units delivered and tested
Patch panel plan discussed (modification from TDR) – demands more ac/dc convertors.
June 24, 2014

7. uHTR Status Data links in pre-production cards –
Receivers work at 4.8 Gbps.
Trasnsmitters work at 6.4 Gbps
Tests with CPT7 and oRM successful.
Green light for production received in May.
Enough to start full crate operations next week
June 24, 2014

8. Modifications in uHTR 2 + 8 uHTR cards (v 1.3) assembled.
RX0 PPOD performance was Gbps
But 4.8 gbps performance excellent – met requirements
- Frahm/Jeremy
PCB with new design (v 1.4) - under production
Value of 4 resistors changed on power mezzanines
Insufficient trace width in power supply to fpga’s addressed.
June 24, 2014

9. Status HF
Booster wires added on v1.3 to address the problem- 6 are now at CERN
Power mezannines for HF 44 sets produced in India, and testing going on – 16 sets already tested.
FPGA – 52 sets in hand and all components purchased
3uHTR (v. 1.4) pcb’s is completed. Assembly going on Bangalore factory – July first week.
Production of 50 pcb’s v 1.4 underway.
Targeting early August for 50 cards.
June 24, 2014

10. uHTR for HB/HE Power mezannines for HB/HE produced in US
Pre-production of Control Mezzanines for HB/HE + HF completed in US. (10+60)
-5 sets have been shipped to India for integration
-Rest 50 to be shipped next month to India
Preproduction uHTR in the US is underway
June 24, 2014

11. Firmware
New version (a year old from Wisconsin) of MMC (v2.15) have been incorporated into the standard uHTR firmware.  It will
-Fix the "many uHTRs" crashing issue
-Allow reloading the firmware from the flash via MMC
-Provide access to the backup FLASH image space.  Care to avoid potential corruption of the backup flash image is needed
-Make crate-labelling valid after just an FPGA reload, without -requiring the module to be unplugged and replugged.
June 24, 2014

12. Software work and Mapping
Software work on unpacker and electronics map (readiness for 2 anode readout from YETS 2015/2016)- Student from Iowa
We need to understand the question of LUT’s for HF in online database with high priority
June 24, 2014

13. AMC13XG(XG=10 Gigabit)
30 AMC13XG produced and tested – 14 shipped so far
Testing going on a 904 – plans for sending the data to central DAQ via opical link
June 24, 2014

14. uTCA Rack Layout - Kellogg
June 24, 2014

15. uTCA rack layout
For HF uTCA crates we will NOT move the existing VME crates but instead utilize the top rack meant for HBHE.
This will avoid fibering work and keep the existing HF VME infrastructure.
The layout – the panel ( Aspiro power supply) for -48 V supply to uTCA crates will be done by technicians soon.
The uTCA crate no. = VME + 20
June 24, 2014

16. Optical Margin Tests @904 & P5
Optical Sensitivity Verification of PPOD
Results for batch of 24 PPOD’s analysed.
They are not as good as the first batch (BB
series), but not as bad as the next (BC).
June 24, 2014

17. Slow Controls
A preliminary version of uTCA slow controls is ready (next slide) – MSU & DESY
- WinCC OA (formerly PVSS) sytem at 904 using the HCAL uTCA crates there. Used a windows PC which is not publicly accessible.
ngFEC work (DESY)- whole chain is working
GLIB card – end of production
Replacement card – FC7 is proposed – to be made available in next few months
June 24, 2014

18. June 24, 2014 Condition database Configuration database
PVSS (WinCC OA)
control, monitoring, visualization
Connection to microTCA electronics is realized
as a chain
PVSS – DIM server – System Manager - mTCA
PVSS DIM client
DIM server
DIM server and WinCC OA project are developed and installed on WIN7 (64 bit) machine
Wisconsin System manager works under LINUX
Software are debugged and checked on DESY test-stand and HCAL test-stand in Bld. 904

20. Plans for Slow Controls
Plans to install slow control and connect it to test stand.
Windows 7 (64 bit machine required )
In autumn Point 5 – 2 computers would be required
ngFEC work
Replacement card FC7 - experience
A dedicated uTCA 905/P5 for development & integration.

21. Summary Significant progress this year.
Will start full crate operations next week.
We expect to have stable operations by August

23. HF VME Crates CMS HCAL s2f02/top HF S2-13 Phi=10-130
CMS HCAL s2f05/bottom
HF S Phi=
CMS HCAL s2f07/top
HF S26-36, Phi=250-10
June 24, 2014

24. AMC 13
A new firmware to support 1,2 or 3 independent event builders each feeding a separate DAQ link
Will remove the limit on event fragment size from each AMC card
Will include the final CDAQ link firmware, supporting 3 links (will then get a good idea of resource useage)
First attempt at full crate test in 904 – problem in clock/TTC alignment – (firmware soln. already there)
A new release of the T2 board is planned – and funding has been released for the prototype new design
Based on aggreement on Funding for AMC13 project – production of new batch of modules.

26. Power-Mezzanine Testing @Saha
PM is mounted on the test board built by Minnesota
The configuration allows us to monitor the temperature, voltage and current drawn by the PM/APM
Test carried out for 39 hrs for each PM/APM to monitor its stability
2 more boards, have been setup which will be used for production and pre-testing.
