2. Outline
Readiness for HST and YETS
Budget
Summary

3. HST Permanent installation Temporary installation FESA classes
One BTV in L4T (AD type): Ready and interlock tested
Charge measurements on the stripping foil : Ready
Prototype board is installed. 2nd prototype design finished.
Expert GUI in preparation
Temporary installation
Two FBCTs - Ready
One BTV system for foil inspection – Ready
Two BLMs: Diamond + Ionization Chamber - Ready
H0/H- measurement from dump: Ready
Mechanics: Ti plates assembled and fixed on dump – System will be validated once installed in the vacuum tank
Prototype board is installed (same as stripping foil)
FESA classes
Ready

4. EYETS 16-17 Readiness for Linac4 connection
Monitors
BI.SMV position measurement plates - Ready
BI.BTV30: Modification due to new septum
ECR , page 6: it will be done “in the framework of the installation of an upgraded PS Booster injection system”.
BTVs: Beam Profile and Foil Inspection - Ready
H0/H- beam current monitor - Ready
Mechanics parts: validation after HST, with minor design review of mechanics
Electronic board: same as HST. Aim at series production (10 boards) during EYETS
BLMs
Ionization Chambers: Ready
Diamond detectors: Expected delivery: Oct Aqn chain: Ready
BR.BCTI in 8L1: injection efficiency with Linac4
Electronic board at pcb design stage. Commissioning in laboratory test bench in October
Work Dose Planning for reshuffling the monitors in radioactive workshop: DIMR 1 (meeting with RP done)

5. EYETS 16-17 Readiness for PSB upgrade [1]
Monitors
BTMS: Ring trajectory: No show stopper
Low intensity resolution measured to 0.6mm with 8E9 charges.
Main remaining issue concerns “shaved beams”, which requires gain change during the cycle, which upsets the PLL. Solutions identified but still to be tested
Front end hybrid and LNA: in production
Wire scanner: prototype in 4L1 - Ready
Functional specifications: draft.
Electronics module prototype ready
Mechanics: First assembly completed (3 weeks delay wrt plan)
Todo list: motor test, vacuum acceptance, laser-based calibration, assembly of 2 additional systems for more tests
ECR: Approved
Flat ICs in L3 sections - Ready
ECR: draft
PSB and PS are upgraded at the same time. 60 kCHF extra FSU cost to be paid by LIU
Functional specifications: reached common agreement between PSB and PS. To be released

6. EYETS 16-17 Readiness for PSB upgrade [2]
Monitors
Tune pick-ups- Tight schedule for installation during EYETS
ECR: draft
Drawings: now in the controls/approval process
Production: planning to be discussed with EN-MME
Wide band BPM in BTP line - Ready
Mechanics: Produced and being assembled.
ECR : Approved
BR.BCTDC:
New electronics not yet validated : low frequency crosstalk from other rings (1%).
A lot of work took place in 9L1: something has changed in the machine (RF bypass tested: OK)
Investigations ongoing (Shielding, filtering). Short machine access requested (15-30min).
Further installations on hold until problem understood.
New housing for BT.BTV30 - Ready

7. Spending Profile and 2016 budget
New spending profile based on the last re-baselining excercice: LIU-PSB Baseline 7
Budget percentage figures = “Commitments incl. pipeline”
TIDs for cabling jobs = 627 kCHF, included for this year but not committed yet.
BWS final cost: to be finalized
FSU for BLM installation: extra budget request

8. Summary Readiness for HST
Mechanics and monitors Ready for beam commissioning
Readiness for Linac4 connection and PSB upgrade
All mechanics and monitors are ready for installation during EYETS but….
the tune PUs: very unlikely !!
the DCCT electronics: installation on hold until problem understood
Budget
LIU-PSB Baseline 7: Minor adjustments yet to come (FWS, FSU)
Four WUs left after EYETS 16-17
YETS 17-18: SEM grids for injection matching  design to start now
LS2: 1)BT.BTV10 2)BWS 3)BLMs in PSB extraction lines  no showstopper
