Hello Probir,
<div class=""><br class="">
</div>
<div class="">Technically I understand that “it is safe" to leave the magnet unattended at 250 A, but unexpected things can happen. But the main point here should be the need to have them ON. I did not hear a good motivation to do so. By next Tuesday/Wednesday
we will know more about the machine schedule, but even optimistically, if we start on Monday 8 am, as it is on the white board now, we will not need that magnets until late afternoon.</div>
<div class="">Another point I want to make is about taking cosmic date, straight tracks, is this arrangement with the magnets at 250 A was discussed and agreed upon with everyone. People (central tracker for example) may want to run cosmic calibrations over
the long down time before the start of the run. </div>
