The National Ignition Facility and TMC Team Up Again.

In 2000, Lawrence Livermore National Labs came to TMC with a daunting task: manufacture504 eight-foot optical tops for its National Ignition Facility (NIF) Preamplifier Beam Transport System (PABST). Not only was this perhaps the largest order ever for optical tops, but the tops had to be technically flawless, meet stringent cleanliness, rigidity, and flatness specifications, be cost-effective, and be delivered quickly. TMC met the challenge.

Because of the overwhelming success of the earlier phase of the project, NIF has again chosen TMC for the project’s next major phase: design and build the Preamplifier Module (PAM) optical tops and housings.

TMC will design and build a complex, 15-foot-long, “T”-shaped, coupled optical table system with an integrated stainless steel housing to control acoustic noise, drafts, dust, and electromagnetic interference. This optical table structure will support the PAM optics. PAM has a total of 48 units that receive a “seed-type” pulse from the Master Oscillator Room and perform certain amplifier functions. The 20-joule output from each PAM goes into ISP, which is a pulse-shaping function.

In the project’s earlier phase, TMC optical tops were used to support the optics in the PABST. The PABST splits the PAM beams into four equal beams, creating a total of 192 18-inch-diameter beams. These pulses then enter the Main Laser Bay where they undergo multiple pass amplifications in the slab laser amplifiers before passing on to the target chamber.

TechCast™ is an ultra-high-stiffness platform created specifically for scanners and other fab equipment. The platform combines TMC's proprietary laminated steel plate construction with a high-strength, resin-aggregate core.

Features:

• Modular design. Can be combined with
  a variety of TMC stands to accommodate
  any floor height
• Pre-engineered in close cooperation with
  equipment manufacturers to ensure spec
  compliance and utility compatibility
• Engineering support. Simply specify the tool, floor height and sub-floor type.
  We do the rest.
• Support stands compatible with a variety of floor heights, sub-floor geometries and “pop-out” patterns
• Cleanroom-compatible construction
• Precision manufacturing method assures a much flatter surface than concrete.
• Part of the TMC Quiet Island® family of products
  

Benefits:

• Cleaner construction than concrete, all stainless steel exterior. Top may be drilled and tapped.
• Easier and less expensive to install than concrete
• Support stand system does not “block-out” complete tool footprint.
• Portable, may be moved as fab requirements change
• Lower cost of ownership (reusable components)
  

TechCast™ is custom designed to meet tool and site requirements and is guaranteed to
meet commercial scanner floor stiffness specifications (upon review of site-specific
floor data). In fact, the platforms are designed to exceed the stiffness of the fab floor towhich they are typically mounted.

TMC’s integrated steel and stainless steel acoustic enclosures are custom designed to provide maximum attenuation for precision instruments such as SPMs, microscopes, interferometers, and other metrology tools that are most sensitive in the low frequency range of 5 to 50 Hz.

Features:

• stainless steel or powder-coated steel finish
• acoustic attenuation up to 40 dB
• fully integrated with our active or passive vibration isolators
• incorporates structural base frames, TMC CleanTop® breadboards and isolators, RETMA racks, and other structural elements
• optional features: hinged panels, glass windows, electrical grounding, and casters
• custom designed for OEM applications
• Finite Element Analysis (FEA) capability
