Rapid Turnaround of Experimental Data

Rapid turnaround of data is essential in conducting experiments at LLE and is made possible by the use of a new "film." Although the Omega Laser Facility conducts a one hour shot cycle, the configuration of the next shot is sometimes delayed until film processing is complete. A new approach using radiographic film provides critical feedback to experimentalists within minutes. Shown with a batch of processed radiographic film is principal investigator Channing Huntington (LLNL), along with scientists Hye-Sook Park (LLNL), Damiano Caprioli and Anatoly Spitkovsky (Princeton University), Gennady Fiksel (LLE), and Dmitri Ryutov (LLNL). They are examining data from an OMEGA EP shot as part of their study of astrophysical collisionless shocks.

OMEGA EP Fires Five Beams

Seen in the upper left are four beamlines of OMEGA EP firing during a target shot. Riding along with those four beamlines is the 4ω probe illuminated in its housing in the lower right and next to the grating compressor chamber. The green irradiation stems from the frequency conversion of the primary infrared beam to the second harmonic or 527 nm. Remotely triggered, the image was captured from the top of the target area structure with no bay lights on.

03/25/13
Programmable Spatial Light Modulator

Installed and being activated on OMEGA EP Beamlines 3 and 4, the programmable spatial light modulator (PSLIM) is being used to improve output beam uniformity, which currently limits UV energy delivered to target. PSLIM is a high-resolution, closed-loop beam-shaping system that consists of a spatial light modulator (shown above held by Matthew Barcys) installed at an image plane in the front end of each beamline. The spatial light modulator alters the beam profile by applying a phase term in a 2-D array to the beam such that a prescribed amount of energy is removed at the next spatial filter in the system. A dedicated, custom-built, wavefront sensor is used to provide feedback during beam shaping and achieve the desired near-field profile without adversely affecting the wavefront. Shown are (left to right) Seung-Whan Bahk, Matthew Barczys, and Mike Spilatro.
