Re: Muon-On-Request

[Michael Barnes <barnes@triumf.ca>]

Dear Peter,

The kicker was originally designed to operate with pulse widths as small
as 200ns. With the overcurrent protection circuit I requested that you do
not operate below approximately 400ns pulse width. One reason is that the
overcurrent circuit will not be active for pulse widths below about 400ns
(due to delays). However there may also be a more serious problem, again
associated with the overcurrent protection/trip circuit, which I will have
to check my notes about.
Please remind me what operating conditions you would ideally like for the
Muon-On-Request mode. Thanks.

Best regards,
Mike
