New photomultiplier 9320KFLB for neutrino detection applications
The 9320KFLB is a compact, 78mm active diameter, curved window photomultiplier for use in multi-pmt optical modules for underwater, and similar, neutrino telescopes. The length of less than 100mm enables up to 31 pmts to fit into a standard 17 inch glass pressure sphere resulting in a significantly increased light collection area and directional sensitivity compared to single, larger, diameter pmts.
PDM02-9111-TTL Photo-detector Module
The PDM02-9111-TTL is a rectangular format photon counting module incorporating a high sensitivity, low noise, 22mm diameter photomultiplier, a fast amplifier-discriminator, and a low power high-voltage supply. The combination of high-speed electronics and fast photomultiplier with low dark counts enables a wide dynamic range to be achieved.
PDM9107-CP-TTL Photo-detector Module
The PDM9107-CP-TTL is a photon counting module incorporating a high sensitivity, low noise, 29mm diameter photomultiplier, a fast amplifier-discriminator, and a low power high-voltage supply. The combination of high-speed electronics and fast photomultiplier with low dark counts enables a wide dynamic range to be achieved.
HV Bases make photomultipliers even easier to use
A new series of HV Bases solves the problems associated with meeting the high voltage requirements of photomultipliers. A wide range is available for photomultipliers from 29mm to 130mm diameter and with postive and negative HV polarity options. The units operate from a low voltage supply and the HV is control by a 1:1000 analgue input. The main features are low noise, low pwer consumption and optomum dynamic range from the photomultiplier.
MCS-CT3 Multi-Channel Scaler/Counter-Timer
A new, wide bandwidth, Multi-Channel Scaler/Counter-Timer for time-resolved TTL pulse counting applications such as photon counting. When used with a compatible amplifier-discriminator, such as the new AD8, and a suitable photomultiplier, it forms the basis of a wide bandwith photon counting system.
The AD8 is a new, high sensitivity, wide bandwidth, amplifier/discriminator which is compatible with the MCS-CT3 Multi-Channel Scaler/Counter-Timer. When used together, the AD8 is powered from the MCS-CT3 via the USB connection and no separate power supplies are required, making it very easy to use.
