  As SCRF particle accelerator technology advances the need for "low
particulate" and "particle free" vacuum systems becomes greater and greater. In
the course of the operation of these systems, there comes a time when various
instruments have to be temporarily attached for diagnostic purposes: RGAs, leak
detectors, and additional pumps. In an effort to make the additions of these
instruments easier and more time effective, we propose to use KF style flanges
for these types of temporary diagnostic connections. This document will
describe the tests used to compare the particles generated using the assembly
of the, widely accepted for "particle free" use, conflat flange to the proposed
KF style flange, and demonstrate that KF flanges produce comparable or even
less particles.
