[Dsg-hallb_magnets] Signals from magnets to beam FSD system

[Pablo Campero]

Dear Ruben, 

After discussion, we can say that the easiest way, is providing a Magnet Current signal. However we can provide both, Hall probes and Magnet current signals. 

Best Regards

Hi Stepan, 

We will have access to two sets of signals per magnet as follows: 

1. Hall probes (6 on the Torus and one on the solenoid) 

2. Magnet current 

In what format do you need these signals? 

Nick, Pablo, 

Which of these 'Magnet ON" signals would be easiest to provide to Stepan? 

Regards 

Ruben

Hello Ruben, 

We need to have signals coming from out two magnets, torus and solenoid, 
to interlock with beam delivery. We do not want to run beam on the target 
with magnets off, especially solenoid. Of course this interlocks can be 
masked 
for special cases, but they should be there for normal runs. 
Who can provide that signals, it can be from power supply or hall probe, any 
thing that indicates magnet is on or off. 

Thanks, Stepan
