Target and beam alignment are accomplished using the chamber center reference system (CCRS), the target alignment sensor (TAS), and TARPOS, positioned around the Target Chamber as illustrated in Figure 5-1. Details on the individual components and procedures are available elsewhere, but a summary is provided here.

2019年1月24日 · The National Ignition Facility (NIF) is the world’s largest, most powerful and energetic laser, composed of 192 laser beams. The beams are used to complete high energy density (HED) physics by compressing targets on the order of 2 …

Target Alignment Sensor (TAS) Systems Manager Edwin Casco uses collimated light from an eye-safe lamp to verify alignment and clearances inside NIF’s TAS4 target alignment sensor. The TAS is a precision optical device inserted into the Target Chamber center by the target alignment sensor positioner (TASPos) to facilitate both beam and target ...

2022年6月28日 · The high precision fully calibrated TAS can easily be knocked out of alignment during these installs and reinstall exchanges and being transported in and out of the NIF. The Miniature Calibration Station System was developed to verify that the critical calibration parameters have been preserved during every TAS exchange.

2016年7月27日 · A key instrument for achieving this level of precision, a new target alignment sensor, or TAS, was installed on NIF in July that should go a long way toward streamlining the process. For successful ignition experiments, NIF’s 192 laser beams and targets must be aligned within a tolerance of about 20 microns—about one-fifth the diameter of ...

NIF operators acquired simultaneous positioning stability for all three NIF target positioners—the TarPos, the cryogenic TarPos, and the dual-purpose Target and Diagnostic Manipulator (TANDM)—in the Target Alignment Sensor (TAS) during the December 2016 facility maintenance and reconfiguration (FM&R) period.

This section lists NIF project Documents, DOE and other government orders, codes, and standards, and national consensus standards which are applicable to the Target Positioner Subsystem. Applicable LLNL standards are

2012年10月15日 · Beam and target alignment are achieved with the Target Alignment Sensor (TAS). The TAS is a precision optical device that is inserted into target chamber center to facilitate both beam and target alignment. It incorporates two camera views (upper/lower and side) mounted on each of two stage assemblies (jaws) to view and align the target.
