8. AFT attenuator test
During the first operations we have found some problems with the attenuator;
During the e-meter work period we start some test on the attenuator.
Review SPARC

9. STATUS of the waveguide power attenuators
● The attenuators have been intensely power tested.
● The design power levels have not been achieved.
● Internal discharges occurred at about 10 ÷ 15 MW input power
● Discharges take place in the circulator section that contains ferrite bars.
● This could be due to excessive
outgassing rate of the ferrites
under high RF power operation.
● Two units have been already
delivered back to the manufacturer
● A meeting with the manufacturer
is foreseen next week in Germany

11. The attenuator have been sent to AFT to solve the problem;
The next week we will go to the AFT to talk about the problem.

42. Control system
The use of the control system has been totally satisfactory;
All basic window for the magnet are developed and used
Some specific window to use in automati operation with the e-meter are developed;
The automatic acquisition are tested;
The first version of elctronic logbook are used satisfactory.
Review SPARC

43. New feature for the control system
New e-logbook based on SQL database are developed;
New class of element are introduced and wait to the with the beam.
Review SPARC

44. Diagnostic The image diagnostic are completaly tested;
Toroidal current monitor are tested;
BPM are start develop with the hardware;
Some new diagnosti are planned and installed just after the gun.
