In Situ Elemental Microanalysis: Beam-Size Characterization Via Resist

Completed Technology Project

Project Description

Project Image  In Situ Elemental Microanalysis: Beam-Size Characterization Via Resist

This proposed effort seeks to upgrade the Ka-band (35 GHz) transceiver of the GSFC High-altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) radar so that it can be paired with another GSFC W-band (94 GHz) Cloud Radar System (CRS) as an airborne simulator for the Decadal Survey Aerosol Cloud Ecosystem (ACE) spaceborne radar. The technical objective is to utilize cutting-edge high efficient solid state power amplifier and low loss front-end to improve the HIWRAP Ka-band system performance.

We propose to characterize the electron beam spot size and spatial stability using an electron beam sensitive polymer to measure the beam diameter and position over typical integration time scales. Photos and micrographs of the resist pattern will clearly illustrate the beam characteristics, thus demonstrating the feasibility of microscale mapping and directly addressing a concern of the ROSES PIDDP reviewers.
