Features

G Thermoelectric cooling using Peltier elements G About -30 °C cooling temperature (with +20 °C cooling water) G Evacuated, double-pane window with heater for frost prevention G Built-in electrostatic and magnetic shielding (C4877 Series) G Water shut-off protection to guard the Peltier elements G Stable operation due to a regulated power supply 102 The C4877 series and C4878 series are thermoelectric coolers constructed with enhanced electrostatic and magnetic shielding (C4877 Series). This minimizes the influence of external noise on the photomultiplier tube and thus significantly improves photometric accuracy. These coolers offer user- friendly functions such as easy temperature control and pilot lamp blank- ing. The C4877 series is designed for use with 51 mm (2") or 38 mm (1-1/2") diameter head-on photomultiplier tubes, and the C4878 series for TACCF0161 Cooling Heat Exchange Medium Amount of Cooling Water Cooling Temperature (with cooling water at +20 °C) Temperature Controllable Range (with cooling water at +20 °C) Cooling Time Optical Window Material Applicable PMTs (Optional) Applicable Socket Assembly or PMT Holder (Optional) Weight C4877 Series C4878 Series C4877 Series C4878 Series Parameter Value/Description Thermoelectric cooling using Peltier elements Water

When used with a photomultiplier tube having an Ag-O-Cs photoca- thode in DC mode, the dark current can be reduced to 1/200 of its normal level at room temperature. In cooling a photomultiplier tube one sometimes encounters problems such as dewing on the incident window and leakage current on the socket or base of the tube. But these problems are eliminated by use of an evacuated, dou- ble pane window and custom socket assembly. The C659-50 series is designed for 38 mm (1-1/2") and 28 mm (1-1/8") di- ameter head-on photomultiplier tubes. The C659-70 series is specifically in- tended for use with 28 mm (1-1/8") diameter side-on photomultiplier tubes.
