1. Testbeam Planning Common to all testbeams:
Silicon detector construction and preparation:
Anne-Laure, Cinzia, Elias, Gennaro
Planar detectors:
Neutron irradiation tests (old detectors) in Ljubljana
Delivery of new detectors expected end of May
Temperature studies
Planar/3D detectors:
Delivery expected in March
Irradiation tests in PS
Pure 3D detectors:
Delay with etching machine
Delivery later in the year

2. Electronics:
Angela, Walter, technician from Brunel, iranian post-doc ?
VFAT development
Board development
Hardware of the later electronics chain (2 copies: X5, SPS)
(buy, partly develop)
DAQ, trigger, online computing:
Emilio, Hubert, Mario, [need more manpower]
Hardware needs
Need 2 DAQs (X5, SPS) as identical as possible,
but specific items for SPS and X5
(SPS: BPM as trigger, 40 MHz synchronisation;
X5: silicon telescope ?)
Need to discuss strategy (together with electronics)
 arrange meeting between Emilio, Walter, Mario, …?
Offline computing:
Valentina, Hubert, Mario
Depends on b, c.
Depends on test programmes for X5, SPS

3. Specific to SPS Coasting Beam Tests:
Test programme
Mario, ?
Cables, infrastructure:
Anne-Laure, Daniela
Cables done
Patchpanel being done
Anything else before end of shutdown?
Roman Pot mechanics:
Marco O.
Cooling:
Friedrich
Roman Pot controls:
Daniela, Mario, Marco O., Walter in cooperation with SPS main control
Veto electronics for RP movement
RP control from counting room near cavern, contact with MCR

4. Coasting Beam Test Programme
Two shifts à 8 hours:
Understand the system
- Adjust DAQ timing w.r.t. 40 MHz clock signal
- Adjust trigger from Beam Position Monitors (BPM).
- Calibrate RP alignment using BPM and rate measurements.
RF pickup, trigger capability, tracking studies
- Measure S/N ratio (detector prototypes with APV25 chip)
- Measure trigger purity (trigger on Si planes with VFAT and verify
with tracking planes)
- Measure trigger efficiency by monitoring one plane with the other 3.
- Try different trigger logics (3 out of 4, 4 out of 4, etc.)
- Record proton tracks detected by the planes with the APV25 chip
and reconstruct them offline.
- Try to Fourier-analyse hit time distribution and look for
components corresponding to the beam structure

5. Roman Pot Configuration
Beam Parameters
1 – 8 bunches (spaced by 23 ms – 2.9 ms)
Emittance N ~ 1 m rad
up to 0.6 x 1011 protons per bunch
Energy: 270 GeV (as high as possible)

6. Specific to X5:
GEMs:
F. Sauli, L. Ropelewski, Kari, possibly Genova technician
October period
Independent DAQ?
T1:
Genova group
Independent
Silicon Tests:
First: Need test programme & strategy (next slide): everybody
Then:
Support mechanics: Marco O.
Cooling: Friedrich
Silicon telescope (if needed): Mario

7. Test Programme for X5: Aims
Prepare full-size detectors, electronics and DAQ for SPS tunnel
Need to identify  10 good detectors of each technology
(4 with VFAT, 6 with APV25)
Measure S/N
Measure efficiency, edge definition
Measure resolution
Want to vary temperature???
Setup Issues
Need support for 2 x 10 planes
(full 3D and planar/3D unlikely to arrive at the same time);
use pot parts of RPs?
Options for reference system:
Self-referencing plane arrangement
Use Silicon Telescope (implications on DAQ)
Both
Trigger scintillators:
Detector area: ~ 48 x 25 mm2
Have 50 x 50 mm2, 10 x 10 mm2 scintillators: adequate?

8. Arrangement Options
Staggered
cannot use pots for mounting
measures only the edges of the upper planes

9. Bilateral
With Telescope
Better resolution (< 10 mm)
Space in the centre with long baseplate ~ 55 cm (sufficient?)
Investigate DAQ issues (e.g. timing)
