2. BI project coordinator role
Bi-directional flow of information between project and BI group
Technical coordination of BI work (installation and hardware, software and beam commissioning planning)
Reach agreements with BI HW/SW experts about implementation details and ensure decisions are followed
Ensure functional specifications, design and budget estimates are followed
Ensure layout drawings are produced and updated

3. AWAKE project background (experiment)
AWAKE general meeting:
Important points:
P+ beam >100GeV required (only
Two CERN sites identified:
West area and CNGS
CNGS favoured due to radiation concerns
BI-TB
AWAKE TB#1
AWAKE TB#2
Milestones identified:
Phase #1 - HWC: Q2 2016
Phase #2 – HWC: Q2 2017
BI asked to detail intermediate steps
Collaborations (MPI)
Provide plasma-cell and diagnostics
AWAKE TB#3
BI asked to identify existing solutions and where studies are required and collaboration is desired
Points covered today

4. BI resources Funding: Manpower: Total: 780kCHF
650 kCHF for proton beam
130 kCHF for electron beam
Manpower:
New fellow in BI/PM to work on spectrometer and BTV (01-Sep-2014)
New PJAS in BI/QP to work on BPM electronics
Reuse existing detectors, cables, electronics and software (when possible)
Some work for dismantling, installation, commissioning

5. AWAKE project for BI #1 Single P+ bunches at 450GeV (3E11)
SPS -> TT40 -> TT41
TT40 already ok (used for B2/TI8)
BPM, BCT, BTV, BLM
TT41
BPM electronics for CNGS (10usec batch) needs modifications (PJAS requested) – hope to reuse cables
Reuse analogue filters from TT2/TT10?
New electronics (TRIC) for BCT
Old cables and electronics for BTV and BLM (minor modifications)

Lars K. Jensen BE/BI/SW

6. AWAKE project for BI #2
BI detectors upstream of plasma (p+, e-, laser)
TT41 (p+)
TT43 (e-)
Laser
TT43 (e-)

7. AWAKE project for BI #3
BI detectors downstream of plasma (p+, e-, laser)
BTV (P+, e-, laser)
BPM (p+ (1, 2), e- (1))
Beam
Layout ‘CERN’
Spectrometer + electron-dump
Plasma-cell exit
Layout ‘MPI’
Beam

8. AWAKE project for BI #4 Electron source diagnostics
Specified (existing PHIN instruments)
1 BCT at source
3 BPMs for position (1 for phase)
1 multi-slit device for emittance measurements
1 BTV for quad scan
1 BTV for spectrometry (in electron beam-line TT43)
1 Faraday-cup also acting as electron beam dump
10/07/2014
Lars K. Jensen BE/BI/SW

9. AWAKE project for BI #5 Dedicated electron-beam line
Specifications for instrumentation
10 dedicated BPMs (one per quadrupole)
40mm aperture, 100um resolution
CTF inductive BPMs believed suitable
Options:
Reuse CTF devices (10cm long) including acquisition electronics
Production of new (20 KCHF each)
Analogue front-end electronics require changes (single bunches) (collaboration?)
10/07/2014
Lars K. Jensen BE/BI/SW

10. AWAKE project for BI #6 Synchronisation (p+, e-, laser)
Light emission appears only choice (streak-camera)
Select CCD (beam setup) or streak-camera with motorised flip mirror (CTF solution)
Choice of screen material to do to be made
What’s believed to be ok (CTF experience):
OTR screen for p+ and laser
Cerenkov screen for p+ and electrons

11. Planning Latest (short-term): https://edms.cern.ch/document/1396078
Milestones for BI
Dismantling of CNGS equipment for tunnel digging (CE: 22/7)
BI/ML: done
Tunnel installation of TT41 for phase 1
To be finalised (Q3 2015?)

12. Actions
Design and test electronics for single p+ and e- BPM in TT41/TT43
BI/QP Q (PJAS)
Assemble 5 additional BPMs from spares
BI/ML Q1 2015
Decide on electronics for ‘critical’ BPMs and request cables/fibres
BI/QP Q4 2014
Design and integrate optical line for streak-camera from upstream BTV
BI/PM Q (new fellow)
Study screen material for p+, e- and laser
Organise BI visit to CNGS areas to identify racks and cables/fibres
L. Jensen (Q3 2014)
