Accelerometers
Columbia Research Laboratories
The force balance accelerometer has a classical critically-damped, second-order frequency response. There is no peaking in the response but simply a smooth roll-off above the natural frequency. This property along with the excellent characteristics of the "HP" torquer design makes Columbia accelerometers the best choice for demanding applications where precise DC and near-DC measurements are needed in demanding shock and wide band vibration environments. Columbia force balance accelerometers are available to cover virtually all applications. Low noise, high output units can be used for seismic structure motion studies while miniature, high range versions are optimum for measuring more violent high G environments encountered in many industrial, aircraft and missile applications.

VHF/UHF Handheld Signal Location Antennas
Type NVF-2
The Type NVF-2 series of handheld directional antennas are used to locate interfering signals or noise in either the 420 – 470 MHz (Type NVF-2A) or the 900 MHz ISM band or cellular telephone bands (Type NVF-2B). Both models incorporate a solid reflector positioned behind a resonated half wave driven element, both elements being mounted on a fiberglass rod with an integral pistol grip. The configuration of the reflector and driven element are such that a deep null in the signal being received will occur when the antenna is pointed in the direction of the signal being radiated. A T-pad resistive attenuator is also incorporated in the antenna mounting enclosure to aid in the direction finding process on very strong signals or when excessive reflections present multiple returns.

Power Supply
The Power Supply Systems are the heart of any experiment. They provide the High voltage and Low voltage required by the detectors and by the related front-end electronics. The quality of the power supply is critical to obtain the best performance from the set-up. The sensibility of modern detectors, in fact, make them susceptible to any even small variation in the power supply, and so features like low Noise, low Ripple and high stability become essential in the design of a performing power supply system. Strong of 40 years of collaboration with the most important research labs worldwide CAEN offers today sophisticated High Voltage Power Supply and Low Voltage Power Supply Systems. The demonstration of this successful long-standing tradition is the “CMS Crystal Award 2009” that CAEN received for the development and production of the power system for the CMS tracker. CAEN offers a wide selection of Power Supplies in different form factors and standards:- For smaller set-ups Standalone or modular (NIM / VME) products or are the ideal fit.- For bigger set-ups, where a high number of High voltages and Low voltages is required, the Mainframe Systems and Boards (up to 48 channels/board, up to 768 channels in a single Mainframe) are the most recommended.
