1. n_TOF “Draft” plans for YETS 17-18 and LS2
D. Macina (EN-STI)

2. n_TOF LOCATION n_TOF Control Room (bld. 603) n_TOF Electronic lab
n_TOF EAR1
(bld. 802)
n_TOF EAR2
(bld. 380)

3. YETS 2017-2018 Mini DAQ in the electronic lab (mostly EN-STI-ECE)
Access: link it to the IMPACT and new SIR course (BE-ICS-AC)
Vacuum: new gauge in EAR1 (TE-VSC-BVO, C. Collomb Patton)
Control Room: installation technical network or trusted machine (EN-STI-ECE)
Consolidation work on the grounding in EAR1 and EAR2 (EN-STI-ECE)
Gas point in EAR2: shield from sun and rain (EN-EA-CT, D. Jaillet, and, depending on the choice, SMB-SE)
n_TOF local team:
Sample exchanger EAR1 (modification of the mechanics)
Alignment (consolidation work on the laser system in both areas)
Add Bismuth filter in EAR1 (to be decided)

4. Mini DAQ in the electronic lab (bld. 547)
new DAQ machine (Mx..)
new timing machine (for generating the triggers)
Merger/proxy machine?? (to send data to CASTOR)
SP-Device card
Ethernet outlet
N.B. Two months delivery for most of the items

5. n_TOF underground areas close to EAR1
Collimator & gauge

6. New gauge in EAR1

7. extra plates and screws
The grounding of this
cable tray should
be understood
Grounding EAR1
The grounding of this
plate should be
properly done
(now we have only
a safety grounding)
These metallic tiles
should be properly
connected
(not with tape)
For example put
extra plates and screws
Common ground between
Bunker and rack area

8. Grounding EAR2 Re-check the common ground
Cleaner ground? Project for LS2?

9. I only cover the n_TOF EAR1, EAR2, CR and Elab
LS2
Three different projects going on:
Replacement n_TOF target (see with M. Calviani)
Irradiation area project (see with O. Aberle, E. Chiaveri)
n_TOF experimental areas: EAR1, EAR2, control room (CR) and electronic lab (Elab)
I only cover the n_TOF EAR1, EAR2, CR and Elab

10. LS2
EAR1: movable collimator (EN-EA-EC, A. Bouvard, Coordination EN-STI-TCD O. Aberle)
New permanent magnet in EAR1 (TE-MSC-MNC, P. Thonet, TE-EPC-MPC, K. Papastergiou)
Move rack area outside beam area
Re-arrange the electronic lab

11. EAR1: movable collimator
This is the collimator in front of the experimental area.
The collimator aperture (80 mm ø or 18 mm ø )
needs to be changed according to
the type of experiment.
The collimator exchange takes about 1 day.
The idea is to have the two collimators
both placed on sliding rails to quickly connect
to the beam pipe the one to be used
for the ongoing experiment.
This reduces the collimator exchange time to
a few minutes (venting and pumping will still
be needed)

12. Permanent magnet in EAR1
Install a permanent (sweeping ) magnet in EAR1.
Gain:
No upgrade of the power supply
No need for maintenance and operation
Presently working on:
Simulation of the magnetic field vs n_TOF physics
Design of the new magnet according to the simulation output

13. Re-locate the rack area
either or
Move the rack area outside the beam area to access it also during beam time:
either to 804-U0-B01 (where the sweeping magnet power supply is located)
or to 804-U0-B02 (old CR)

14. Re-locate the rack area
either OR or
Move the rack area outside the beam area to access it also during beam time:
either to 804-U0-B01 (where the sweeping magnet power supply is located)
or to 804-U0-B02 (old CR)
To be checked:
Cable trays
Rack grounding
~ 50 m longer cables
! old cables need to be replaced with new ones as well as the patch panels even if the rack area is not re-located

15. Re-arrange the Elab Get the whole space in the barrack
Set-up a test bench with:
clean areas
dark boxes
Electronic work
etc
