Tuesday, October 01, 2019, 16:34: All TPs at speed


Conditioning completed over the weekend by RIB operations. The shutter was left closed on the module, so no beam could be seen on the FC. Conditioning otherwise OK.

TM2 has been connected at TCS this morning. helium pressure test on Tm2 HS line is done. No leak.

  2019   Thursday, October 31, 2019, 08:49 Anders MjosConditioning StationRepair  Water leak on non-active cooling water circuit

Yesterday a leak was discovered in the ISAC-I experimental hall. The leak appears to be at the connection between the evaporator and the return water line. 1 in of water was lost from TCS:TK1. The water is currently valved off to prevent further leakage.

A fault reportt has been submitted to mechanical services - awaiting response.


Friday, November 01, 2019

Leak repaired by Mechanical Services. A brass fitting had cracked and was replaced with a galvanized fitting.

Helium pressure leak check on TM2 HS line at TCS is done. No leak. Also, Helium are sprayed to gas line adapter and fittings. No leak. TM2 is connected at TCS. Anode plug on TCS is connected to module 52pin connector. Water system is started. Vacuum pumping down is good. HV cover will be installed today.

Tuesday, November 12, 2019

The FEBIAD source worked well over the weekend. The anode current limit was adjusted twice to stop voltage limiting. About 5E-8 A on the FC with TGHT=580A, TBHT=300A, ANODE=200V,150 mA, COIL=50A. Bias was conditioned to 30 kV
