Hello,

I've just turned on the Magnet to ~100 A to counter electron cloud that
Wolfram Fischer has persuaded for a little while.
( I've managed to persuade the OC Ian to let me do so before they start
injecting. Otherwise, I don't know how long
I'd need to wait before they finish injecting. As of the time of writing,
they seem to have "oscilloscope" problem that they still haven't started. )

The magnet has remained standby or off since Apr. 18 (after I was asked to
shut it down because of the valve problem in the 400 L reservoir). Since
then, as the TPC is not really ready, the Magnet has remained off until now.

The plot attached is show the initial current jump and the coil temperature
response.

Kin
