Week Program & Report

Week N. 20 (2012-05-14 / 2012-05-20), Run Coordinator on duty: Zobov Mikhail

 

MONDAY 14/05

 

1. Work on devil 360 and BTF instrumentation (Stecchi, Foggetta, Control system service staff). See Trouble Ticket.

2. We are waiting when the water conductivity achieves the nominal values to switch on hardware. Checks every 2 hours.

  At 17:00 it was 0.8-0.9.  Expected final check at 8:30 tomorrow morning by Rotundo.

3. Compesator solenoids are cooling down. Expected time for complete cooling - mid night (Ligi)

4. After the water temperature increase till 27.5C it seems that all leakages from wigglers stopped (Checked by Rotundo, Iungo)

 

TUESDAY 15/05

 

1.  Water conductivity check at 8:30 -> the conductivity increased till about 1. It has been decided to change filters.

2. 14:30 All DAFNE magnets are ON (Bolli, Iungo). The water conductivity remains at the limit - 0.95.

     We are waiting for repair of the fan (ventilatore) in the DAFNE hall

3. Cable preparation for clearing electrodes power supplies (Coiro)

4. Much work has been done by Rotundo, Marchetti, Sorgi, Passarelli. The summary below:

 

     a. Sostituzione filtri micrometrici su impianto di demineralizzazione;

     b. Ripristino funzionalità di un condizionatore in sala Dafne;

     c. Messa in sicurezza di un altro condizionatore sempre in sala Dafne;

     d. Sostituzione motore ventilatore UTA sala Finuda

 

 5. DAFNE restart at 16:00

 6. 18:30 Cycling MR magnets because of the residual dispersive orbit (DIPEL102 failed 2 times)

 7. From 19:00 -.. Collision optimization (Milardi, Drago, Zobov, Operators)

 

WEDNESDAY 16/05

 

1. 10:30-19:00... Several hardware problems (minor linac discharges, corrector magnets off, quadrupoles magnets off,

     devils 320, 336, 339, 340, 351, Linac gun, accumulator ring kicker) do not allow smooth collider tuning.

2. From 19:00 Collision optimization (Milardi, Zobov, Operators)
