| === PreparationRun Tue 14/05 === GISMO electronics is still there. Thus first we'll have to wait that it's craned down before starting working on the cryostat. We re-pump the cryostat and the big pumping pipe before the intervention. Jpi is growing up a bit after pumping; 1e-3mbar per minute roughly. Not very dangerous, could be outgassing, but I have seen better. Could be a small leak at the O-rings. In any case we have to open later. |
