[ Identification | Description | Input parameters | Output parameters | Links ]

The PBD_BT Instrument

Mockup of 219/B004 PBD

Identification

  • Site: NIST
  • Author: Marcus H. Mendenhall (marcus.mendenhall@nist.gov)
  • Origin: Your institution
  • Date: Current Date

Description

This is a preliminary setup of the PBD, using single-bounce crystals instead of 3-bounce crystals
