Laser surveying team worked till 11. Chamber was too high by 3mm close to the jet target and 6mm by the turbo pump (towards the dipole).&nbsp;

CARME lowered appropriate amount using bolts under CARME feet. Height checked using a laser on the centre point line of the middle flange turbo end and mid point on the front of the chamber (see images). During lowering front foot swapped and valve supports moved slightly to give more clearance for opening. ~13cm clearance for opening the chamber currently.&nbsp;

Pipe and single bellow&nbsp;connecting CARME to dipole replaced by two bellows and new pipe. Rest of open ports on chamber closed.&nbsp;

Thermocouple feedthrough flange installed under the motors flange in the turbo pump section. One&nbsp;internal thermocouple hooked onto kapton cable connected to MACOR and one thermocouple left floating in the chamber. Floating thermocouple corresponds to right output on feedthrough, thermocouple on kapton corresponds to left output on feedthrough.&nbsp;Image taken from flanges at the top of the chamber, quality is poor due to lack of maneouvering space.&nbsp;&nbsp;

Baking frame partially assembled around the chamber. Full assembly requires removing valve airlines to get under the valve pipe, will be done Monday morning. Took measurements for the RGA around the chamber, should be able to fit in multiple positions without conflict with baking jacket.&nbsp;
