Janus Upgrade using brewster angle disk amplifier technology. [Janus laser system]

The Nuclear Test and Experimental Science Program (NTES) has requested that the Laser Program design and price an upgrade to the Janus laser system (JANUS UPGRADE) capable of reliably delivering in excess of 200 joules per beamline in a range of pulse forms to three experiment areas. The facility is to have the following characteristics: three experiment areas, two high energy beams, each with 200--400 joule/1 ns at a wavelength of 1.053 or 1.064 microns, and 125--250 J/1 ns when frequency doubled, one probe beam (0.1 J rated at 30 ps) to be used for interferometry, and reliable operation. The proposed facility would occupy approximately 5600 ft{sup 2} and be located in the Bldg. 174 complex. A block diagram of the entire facility is shown in Fig. 1. The facility is further defined by the Work Breakdown Structure (also shown in Fig. 1). The main elements of the WBS are the conventional facility and modifications thereof (WBS 1), special equipment (WBS 2), the laser (WBS 3), the experiment areas (WBS 4), the controls and data acquisition system (WBS 5), and the project integration (WBS 6). The experiment area has three target chambers and uses diagnostic hardware now in Janus. 12more » figs., 4 tabs.« less
