Establishment and maintenance of a coal sample bank and data base. [Including sample preparation without oxidation]

Retrieval of 5-lb splits of -1/4 inch coal from designated 30-gallon drums was completed. Preparation and analysis of these samples for the second yearly quality evaluation is in progress. After consultation with the DOE Project Manager, two replacement samples were collected. These are the first of the series which will be stored in foil laminate bags. Both of these samples were placed in 30 gallon steel drums lined with polyethylene bags at the mine site. They were equipped with lid gaskets made from Tygon tubing, and 1/4 in. metal tubing fittings to purge and pressurize the drum with argon.

Short wavelength chemical laser demonstration based on N({sup 2}D) chemistry. Final technical report (open access)

Short wavelength chemical laser demonstration based on N({sup 2}D) chemistry. Final technical report

The overall goal of this project was to demonstrate lasing on the NCl(b{yields}x) transition at 665 nm. Our scheme is based on chemical production of excited nitrogen atoms in the {sup 2}D metastable state and subsequent reaction of N({sup 2}D) with Cl{sub 2} to produce NCl(b). Our intermediate objectives were: (1) demonstrate chemical generation of N({sup 2}D), (2) identify and measure rate constants important to the chemical scheme, and (3) demonstrate production of NCl(b) from the N({sup 2}D) + Cl{sub 2} reaction. The program results and accomplishments are summarized in this report.
