Radiation damage experience at CDF with SVX
Abstract The radiation damage experience of the silicon vertex detector used in the CDF experiment during the 1993–1995 collider run is described. The detector is single sided, AC coupled, FOXFET biased, and uses radiation hard readout chips. The detector's noise is seen to increase anomalously with radiation dose.

SVX', the new CDF silicon vertex detector
Abstract The Collider Detector at Fermilab (CDF) radiation hardened silicon vertex detector (SVX') is described. The new detector has several improvements over its predecessor such as better signal to noise and higher efficiency. It is expected to have a radiation tolerance in excess of 1 Mrad. It has been taking data for several months and some preliminary results are shown.

The external muon identifier for the fermilab 15 ft bubble chamber
Abstract An external muon identifier to aid in the identification of muons produced in neutrino interactions in the Fermilab 15 ft bubble chamber has been constructed. Details of design and analysis procedures are discussed. The spatial resolution and efficiency have been calibrated using muons regenerated by neutrino interactions in material upstream of the bubble chamber. A formalism to describe the statistical significance of muon matches in the identifier is developed and tested using tracks from actual neutrino interactions.

Laser pulse stretching via enhanced closed loop control with slow Q-switching
Abstract A pulse stretching technique in a Q-switched ruby laser oscillator is described. The major improvement to our previously developed pulse stretching circuit consists in a more adequate waveform for the feedforward part. This new system gives fairly flat pulses with adjustable duration up to ∼ 100 μs and good coherence length in excess of 11 m. The cavity is followed by several amplifiers and produces light energies up to 8 J for holographic recording of particle tracks in the Fermilab 15-foot bubble chamber. The considerably increased coherence length will find applications in many fields of pulsed holography and its use with fiber optics is particularily promising.
