1. Document : “LHC Orbit System Low level SW procedures” : EDMS ID 1348775. Contains an introduction to the system infrastructure and several low level procedures:1348775 Calculation of the LHC Beam Position in mm: Main difference wrt LHC run#1 are: Update of the coefficients. 2D geometrical corrections. Those coefficients can be found in Andriy’s document : EDMS ID 1342295 (Table 2).1342295 No more multiplication by Kf before geom. non-linearity correction. Tilt expressed as an angle, and not as a cos (45°), to allow generalization to all the BPMs. QA: SW “embedded” offsets and tilts should be specified on this document. D. Missiaen will provide us updated info about offsets & tilts by the end of the year. (BPMD, etc). Temperature compensation: keep as it is implemented now. Hard-coded Some errors were found in the FIP decoding for the “FipOverview” procedure described in the previous document version. Application should be checked. Described procedure to obtain serial numbers of the tunnel cards as human readable numbers.

2. New documents to clarify the mapping between BPMs, FECs and FIP addresses. (EDMS 1342851). 1342851 There will be new BPMs, and some name changes. These changes will be propagated soon to the previous document. Pt 3 : Pt 4 : New monitors for the BGI: BPMWI.5L4.B1 and BPMWI.5R4.B2 Pt6: OldNewComment BPMWE.5L3.B1BPMWG.A5L3.B1Same aperture BPMWE.5L3.B2BPMWJ.A5R3.B1Aperture changes: 61mm a 80mm BPMWE.5R3.B1BPMWJ.A5R3.B1Aperture changes: 61mm a 80mm BPMWE.5R3.B2BPMWE.A5R3.B2Same aperture OldNewComment BPMSBBPMSI.B4L6.B2 Same aperture BPMSBBPMSI.A4L6.B2 Same aperture BPMSABPMSX.B4L6.B1 Same aperture BPMSABPMSX.A4L6.B1 Same aperture BPMSABPMSX.A4R6.B2 Same aperture BPMSABPMSX.B4R6.B2 Same aperture BPMSBBPMSI.A4R6.B1 Same aperture BPMSBBPMSI.B4R6.B1 Same aperture

3. Pt 5 : BPMs in Roman Pots will move from 4L6 to 6L5 and from 4R5 to 6R5. 6L5 and 6R5 already had Totem stations. New names to be defined. Channels equipped with Diode Orbit also seen by the OFC: Duplicated channels for BPMS in Q1. Collimator BPMs.

4. Terminals in the SR buildings? Before LS1, PC in rack BY01. 1)Either we find a new place to install them back There are empty racks in the same row: SR1, SR2, SR5, SR6.SR1SR2SR5SR6 SX4 we can place it in a table in the BI closed local. SR8: empty racks Without place: SR3, SR7 and SR8.SR3SR7SR8 2) Either we replace them by CO centrally managed PC + 1U KVM console installed in a free slot at rack BY05. CO accepts this solution and seems easy to integrate. Prices from 700CHF up to 2k CHF, and typically ~1400CHF.

5. Some KVM consoles: StartTech.com : starting at ~760 USD (17” 1280x1024 display, 1 VGA and 1 USB A) up to 1400 USD (17” 1920x1080 display, 1 USB B, 1 VGA and 2 PS/2). StartTech.com Dell: ref. 331-9437 for 1240 USD (18.5" display, and 1 KVM and 2xUSB interfaces). Dell APC: 17” or 19”, comes with a custom cable at the console end and it has 2 PS/2 + 1 VGA at the other end. APC Tripp lite: 17” 1280x1024 LCD with also a KVM cable kit (VGA + 2 PS/2). 2kCHF at mouser.ch Schroff: 17” 1280x1024, 2 PS/2 or USB, about 1200 euro/piece. Schroff

6. 2 empty racks SR1

7. 2 empty racks SR2

8. SR3 Local ? Drawing is wrong ! No rack empty but these two have many space available.

9. SE5 2 empty racks

10. SR6 Empty rack

11. SR7 Many space available, but magnet interlock.

12. SR8 Empty racks EPC local ?
