Laboratory Astrophysics Using a Microcalorimeter and Bragg Crystal Spectrometer on an Electron Beam Ion Trap

We completed modifications to the new microcalorimeter system dedicated for use on the EBIT at NIST, which included: 1) a redesign of the x-ray calibration source from a direct electron impact source to one that irradiates the microcalorimeter with fluorescent x-rays. The resulting calibration lines are free of bremsstrahlung background; 2) the microcalorimeter electronic circuit was significantly improved to ensure long-term stability for lengthy experimental runs

Micro-Calorimeters with NTD and Epitaxial Germanium Thermistors for High Resolution X-Ray Spectroscopy

This is a progress report for the third year of a three year SR&T grant to continue the advancement of NTD-based microcalorimeters. We highlight our progress to date that allowed us to garner an additional three years of funding for this work.

The Tunable XUV Imager (TXI) Sounding Rocket Payload

The TXI was flown successfully on 21 June 2001 (36.199 US). All systems functioned as planned and image data were acquired and sent to the ground. Unfortunately, due to a parachute failure the payload was destroyed. In this report we summarize results from the flight and provide detailed information on the high resolution X-ray imaging detector which was developed as part of the program.
