33	33	- Liquid Nitrogen refill is required in the cleanroom. For the first fill, 40L of LN2 is required. For refill, every 48 hours, 15-18L of LN2 is required (see Notes section above for more details).
34	34	- Vacuum pump and support for cooling down the cryostat. We do not yet have the dimensions of the vacuum pump (available from LBTO) and how the LN2 refill will take place. If they will be done using long hoses then both vacuum pump and LN2 tank can stay outside the clean tent (see Notes section above for more details).
	35	- We will require UPS connected to the turbo pump when pumping vacuum in the cryostat. UPS which can hold the power for 15 minutes would be sufficient. In case of a power outage, within 15 minutes, one of the SHARK-NIR team members can go to the pump and close the valve preserving the vacuum within the cryostat.
