MercuryiTC & iPS Intelligent control of cryogenic and magnetic environments
MercuryiTC Intelligent temperature controller
The MercuryiTC is a versatile cryogenic environment controller. In its basic form it includes a single channel high-resolution (24 bit) temperature measurement circuit which supports all the standard cryogenic sensors (ruthenium oxide, cernox, silicon diodes, platinum, thermocouple and RhFe). With the constant voltage mode it enables reliable, accurate temperature measurement using negative temperature sensors (NTC) down to below 250 mK. The base unit enables PID loop configuration control of a single heater output up to 80W (40 V, 2 A).
The base unit incorporates a versatile touch screen display with signal widgets (18 widgets) that are user configurable to display any of the internal system signals. The unit is fully controllable by remote command via TCP/IP, USB, RS232 or optional GPIB. Any of the available system signals are also available by remote command.
The base unit is expandable with plug-and-play cards. There are 9 expansion slots, 8 multi-use and 1 dedicated for GPIB. The expansion slots allow the addition of 8 extra temperature sensor cards, or 3 temperature sensor cards coupled with 3 additional 80W heater cards to form a total of 4 independent PID loops. Or pressure sensors cards can be added which can be used to control cryogen flow via Auxiliary (Gas Control) cards.
Please note: The temperature sensor – heater PID loop algorithm also includes a feature to balance a cooling cryogen flow without the need of a pressure card. The MercuryiTC will also support the Cryogen level meter card for monitoring Helium and Nitrogen cryogen levels
Interfaces: Ethernet, Serial, USB or optional GPIB
MercuryiPS Intelligent magnet power supply
The MercuryiPS is an intelligent fully configurable magnet power supply system. It enables automated control of a wide range of superconducting magnets, including NMR, high field, beamline and Vector Rotate magnet systems. MercuryiPS is a bi-polar, high-stability, four quadrant power supply with incorporated quench protection. It includes temperature control of the main high-power sense resistor to prevent output current drift.
The MercuryiPS is fully controllable by remote command via TCP/IP, USB, RS232 or optional GPIB.
MercuryiPS has an on board temperature sensing for diagnostic monitoring of magnet temperature. It also includes an option for LHe/LN2 level meter expansion card, additional temperature sensing cards, and an auxiliary port expansion card.
Modular design: Based on ±60 A modules with ±10 V compliance and can be configured in parallel, series and matrix modes from the basic ±60 A with ±10 V output up to ±600 A with ±10 V or ±300 A with ±20 V output configurations.
Versatile: Communications support a full range of interface options (Ethernet, USB, RS232, and optional GPIB) with downloadable Mercury function library for LabVIEW.
Complete cryogenic system automation: Quench protection and auto-rundown where the MercuryiPS can be programmed to run magnet down safely in event of magnet temperature rise, low cryogen levels or triggered by an external TTL signal.
The MercuryiPS can also be configured to control the system Lambda fridge.
