The Spacecraft Charging and Instrument Calibration Laboratory SCICL is in the process of being updated at Kirtland AFB, Albuquerque, NM. SCICL will be a comprehensive one-stop shop for testing R and D spacecraft solar array coupons, novel materials, dielectric charging, and modeling of spacecraft effects from said materials. The Jumbo space environment chamber has been modified with new high energy electron, photon and ion sources to simulate the space environment. The system includes the ability to mount a variety of probes on an up to four axes motion system to generate accurate characterization of the environmental sources. The first experiments planned for the Jumbo chamber are measuring the charge transport characteristics of insulating materials. This work requires measuring the sample surface potential with non-contact electrostatic probes during exposure to an electron beam. This technical report focuses on the capabilities upgrade to the Jumbo chamber as well as characterization of the various sources and probes used to create and measure the simulated space environment.
