Facilities
Belljar Facility
The belljar vacuum chamber has an inner diameter of 23.75 in. and an inner length of 27.5 in. The base pressure is 10-7 Torr. Using a Leybold Trivac D4B turbomolecular pump and Cryo-Torr 8 cryopump, this chamber achieves a base pressure of 5 x 10-6 Torr in 3 hours.
EP Test Facility 1: Burton Chamber
This facility is 1-m-diameter and 1.5-m-long evacuated to a base pressure of 10-6 Torr by a TPU1500 Pfeiffer turbopump. It has a thrust stand based on a long-period pendulum design which uses the Watt straight-line mechanism. The measurable thrust is 40 µN with 2 µN resolution
EP Test Facility 2: White Vacuum Chamber
This facility is 1.2-m-diameter and 2.1-m-long evacuated to a base pressure of 10-6 Torr by a PHPK TM1200 cryopump. It has a thrust stand based on the NASA GRC null-type inverted pendulum design.
