Evaluation & Upgrades to ARM FFSSP and FCDP

15 June 2011 - 30 November 2011

Lead Scientist: Paul Lawson

Observatory: OSC

Both FCDP and FFSSP probes were acquired by DOE under the ARRA procurement program. These are advanced versions of the FSSP and CDP. Both the FCDP and FFSSP incorporate state-of-the-art electronics that process and record particle-by-particle measurements that are used to remove shattered ice particles, coincidence and additional statistical measurements. The FCDP also incorporates a slit-based optical system that is designed to reduce uncertainties in sample volume determination. SPEC, Inc. evaluated the performance of these ARM probes.
