7h40: mise en chauffe de la machine (modulateur, laser, frigo/chiller, cyclage aimants)

 

*** Programme imagerie X ****

- radiographie en contraste de phase

- Tomographie en contraste de phase

8h40 HV is 'On'

10h13 Beam in the ring. RF Gun phase is 233 dg., Sect. phase is 209 dg. Att. sect. is 2.54 dB, TL/BPM2 x=1.5 mm. RF Cav at 200 kV , phase -38.5 dg.

The FPC phase was adjusted to maximize I3 current (between 25000 and 30000).

10h46 Charges: -145 pC, -145 pC, -160 pC. Have a growing trend.

10h50 The RF gun phase was set to 226 dg. to restore storage and x-ray. The injection is very unstable.

11h43 RF gun phase 219 dg. Sect. phase 209 dg. RF cav. phase -43.5 dg. I3 curr. from 40000 to 50000

12h27 RF gun phase 218 dg. Sect. phase 207 dg. Att. 2.48 dB, TL/BPM2 X=1.5 mm to 2 mm, RF cav. phase -43.5 dg., 200 kV, I3 curr. around 40000 pA

16h45 RF gun phase 215 dg. Sect. phase 209 dg. Att. 2.51 dB, TL/BPM2 X= 2 mm, RF cav. phase -46.5 dg., 200 kV, I3 curr. around 40000 pA

17h28 RF gun phase 214 dg. Sect. phase 211 dg. Att. 2.56 dB, TL/BPM2 X= 2 mm, RF cav. phase -46.5 dg., 200 kV, I3 curr. around 40000 pA

18h57 Stop ThomX
