NA44 (~1989-1996)


NA44 (homepage here) was a second-generation HI experiment. This was a small-acceptance spectrometer optimized for identified single-particle and two-particle (Bose-Einstein) distributions.

We built gas cherenkov threshold counters, an aerogel cherenkov counter and a scintillating fiber T0 counter.

For NA44 (The Focusing Spectrometer), we built 2 pressurized gas threshold cherenkov counters. They are kept warm and are wrapped in a blanket.
We also built a (plastic) fiber trigger counter
We used the NA44 experiment to parasitically do R&D on the use of aerogel for imaging cherenkov application.

This is the test unit, which allowed us to make ring images on photographic film, as well as do photon counting with a single PMT.

In the NA44 control room: Ian Bearden, Toru Sugutate, Nu Xu, Achim Franz, Jehanne Simon-Gillo, Masashi Kaneta, Hubert van Hecke, Dan Zachary, Hans Boggild, Dave Hardtke, Michael Murray.
Down in the experimental area. I see Guy Paic, Hubert, Achim.
(for Cesar: our aerogel work was picked up by Tom Ypsilantis, who then used it in LHCb)
