Digitel™ Small pump controller: The SPCe is a versatile way to fully operate a single ion pump. An LCD pressure/ current/voltage display along with standard serial communications makes the SPCe able to accommodate the needs of basic and advanced users.
Digitel™ Quad pump controller: The new QPC controller offers adjustable output voltage, nano ampere resolution plus up to four independent power supplies, allowing for high current control of up to four ion pumps independently. It has an easy-to-read colour touchscreen LCD display that simultaneously displays pressure, current, and voltage and includes serial and Ethernet communications as standard.
Digitel™ remote TSP/NEG controller: The TSP/NEG controller has an easy-to-read touchscreen LCD display that displays all manual or programmed firing parameters. Manual operation is as simple as pressing one button. Programming is just as easy by viewing all programming options on one screen. The TSP/NEG controller can operate up to 8 TSP filaments or 2 NEG pumps.
Digitel™ Multiple Pump controller: The MPCe allows for high current control of two ion pumps independently or up to four in parallel with 500 mA (1000 watts). At 3U high and a full rack in width, the MPCe is ideal for operating a wide variety of ion pump configurations on any system.
Product Features
LIQUID CRYOSHROUD
The liquid cryoshroud consists of a double walled, type 304L stainless steel cylinder with two liquid nitrogen feedthroughs (.375 in. diameter) with flare type fittings. It provides 1578 cm2 (245 in2 ) of liquid nitrogen cooled surface area that provides pumping speeds up to 12,000 ls-1 for hydrogen (see table). The shroud is mounted on an 8 in. CFF (DN160).
TSP FILAMENT CARTRIDGE
The filament cartridge is mounted on a 2- 3/4” CFF (DN40). The feedthrough supports three titanium-molybdenum filaments and a return path for ground isolation. Each filament contains 1.5 grams of usable titanium and averages 20 hours of operation.
AMBIENT SPUTTER SHIELD
The ambient sputter shield economically maximizes surface area when cooling is not practical or possible. It provides 827cm2 (128 in2 ) of ambient temperature surface area that provides pumping speeds up to 2200 ls-1 for hydrogen (see table). The shield is mounted on an 8 in. CFF (DN160) or a 6 in. CFF (DN100).
