The LVD tracking system chambers

Optical Alignment System for the PHENIX Muon Tracking Chambers

A micron-precision optical alignment system (OASys) for the PHENIX muon tracking chambers is developed. To ensure the required mass resolution of vector meson detection, the relative alignment between three tracking station chambers must be monitored with a precision of 25μm. The OASys is a straightness monitoring system comprised of a light source, lens and CCD camera, used for determining the...

Drift and Proportional Tracking Chambers

The Circumfusion System for Multipurpose Culture Chambers

A self-contained mechanical system for circulating nutrient fluid through 12 tissue culture chambers is described in detail. This system utilizes nonperforated cellophane membranes in the chambers which separate the circulating nutrient from the tissue culture environments. The nutrient, therefore, is dialyzed through the cellophane of each chamber; some cell products are retained in the microe...

LVD: A Lightweight Virtual Desktop Management Architecture

Rapid improvements in network bandwidth, ubiquitous security hazards and high total cost of ownership of personal computers have created a growing market for desktop virtualization. We present the LVD, a system that combines the virtualization technology and inexpensive personal computers (PCs) to realize a lightweight virtual desktop system. Comparing to the previous thin-client systems, LVD s...

Vacuum-cleaning system for isolation chambers.

To encourage the utilization of the isolation chamber as a research tool, the cost of its use should be lowered. Methods and devices must be developed which make more efficient use of the space within the isolator and allow the operator to work more effectively in this confined area. A simple vacuum-cleaning system is described; it consists of a nozzle and flexible hose which connect through th...
