This morning with Manar, we started to clean the floor around the cavity, the outside part of the panels of the housing, and the optical table.
we will continue this afternoon and, in the end, we will make some dust measurements.
do we know who in ThomX is in charge of the cleanness of the casemate (bringing overshoes, sticky floor, cleaning company for the floor,...)?
the motors controller mini-rack has been installed under the optical table.
but it is still not connected to motors or computer.
we saw a chiller beside the optical table... is it the laser amplifier chiller ?
there is also the hexapod controller which is presently close to the wall.
do you remember where is the final place of this controller?
the two vessels of the FP-cavity are presently at room pressure with nitrogen inside.
it has to be put under vacuum (~ 10**-8) before opening the 2 valves which are separating the vessels from the electron ring.
we can't make any Finesse measurement until the vacuum is made and the valves are open.
we discussed with Bruno about that, and he is aware of the situation. He said he will try to pump the vessels as soon as possible
in order to be able to inject a laser on the next opening, next week. |
