1. CNRAD dosimetry and Summary of the TS
Summary of the Technical Stop
Installation have been performed the 10th of November.
CNGS last slot - beam started on the 11th of November at 17:51
End of last slot scheduled on the 21st of November.
Next access will be probably at the beginning of December (to be defined with RP and CNGS coordinator)
Installation and removal of Equipment
TSG45
Installation of the BPM component test in position 451.
N. B: No connection for some optical fibers (control room → TSG4 stations).
Test of optical fiber connections from control room to TSG during the next TS.

2. CNRAD dosimetry and Summary of the TS
Installation and removal of Equipment
TSG46
Removed PLC equipment:
The PLC and PC became inaccessible a few hours after the start of the radiations  no analyse possible.
Removed QPS equipment from position 464 :
Test during slot 4 and 5 did not revealed any failures. The installed equipment worked correctly.
Installation of QPS equipment in position 463:
PhotoMOS AQW210EH: check for radiation induced fast transients. “BricoFIP” test; automatic power cycle of uFIP chip after loss of communication
Test of Ethernet Switch and Wifi cancelled by user due to the uncertainty of the beam intensity for the last slot and due to required modifications for the test setup.

should be low enough to avoid radiation damage

4. Beam Intensity Nominal beam intensity ≈ 2×1013 charges/extractions
Normal test conditions in CNRAD
Preliminary results for the radiation levels at the test locations :
BPM components : Position 451:
Dose ≈ 11 Gy
1-MeV equivalent fluence ≈ 1.1 ×1011 neq/cm2
HEH fluence ≈ 7.7 ×1010 cm-2
QPS equipment : Position 463:
Dose ≈ 1.3 Gy
1-MeV equivalent fluence ≈ 1 ×1010 neq/cm2
HEH fluence ≈ 7×109 cm-2
