MCP ASSEMBLY WITH CENTER HOLE FOR REFLECTRON MS PRELIMINARY DATA MAY 1998 F4294-09 Ideally suited for reflectron mass spectrometer The F4294-09 is an MCP assembly developed for reflectron mass spectrometers. In spite of having a center hole for beam line, the F4294-09 eliminates ringing phenomena which have been a problem with conventional MCP assemblies with a center hole. The F4294-09 thus makes high-speed ion detection possible. This allows a significant size reduction in the TOF mass spectrometer and a dramatic improvement in mass resolution. TMCPF0090 FEATURES APPLICATION Reflectron mass spectrometer Center hole for beam line High-speed response Good output waveform with negligible ringing SPECIFICATIONS GENERAL Value 69.0 27.0 26.4 12 2 6.0 12.0 Unit mm mm mm µm mm mm MAXIMUM RATINGS (Absolute values) MCP Supply Voltage (In-Out) MCP-Out to Anode Voltage Electric Potential at Each Terminal Operating Vacuum Condition Baking Temperature Baking Time Baking Vacuum Condition 2 0.5 MCP-In: -2.5 MCP-Out: -0.5 Anode: GND -4 -6 6.7×10 (5×10 ) Max. -* -* -* kV kV kV Pa (Torr) °C h Pa (Torr) Figure 1: Typical Output Waveform TMCPB0077EA OUTPUT VOLTAGE (5mV/div) Parameter Assembly Outer Diameter Effective Diameter Maximum Height MCP Channel Diameter Number of MCP Stages Center Hole Diameter Center Dead Space Diameter RISE TIME: 328ps FALL TIME: 633ps FWHM : 592ps SUPPLY VOLTAGE (MCP): 1700V * Baking cannot be performed. -4 -6 CHARACTERISTICS (at 1.3×10 Pa (1×10 Torr), Ta=+25°C) Gain at 2.0kV Plate Resistance per MCP Dark Count at 2.0kV 6 1×10 10 to 100 5 RESPONSE TIME (0.5ns/div) MΩ 2 cps/cm Subject to local technical requirements and regulations, availability of products included in this promotional material may vary.
