Star Cryoelectronics

Since 1992, Mr. SQUID has been the standard educational demonstration system for undergraduate physics lab courses.

Mr. SQUID® is a complete Superconducting QUantum Interference Device (SQUID) system based on high-temperature superconductor (HTS) technology. The Mr. SQUID® system consists of an HTS thin-film SQUID chip mounted on a rugged probe with removable magnetic shield, an advanced electronics control box, and a vacuum dewar flask. The Mr. SQUID® probe is immersed in a liquid nitrogen bath in the vacuum dewar flask, and the Mr. SQUID® electronics control box is used to display the SQUID characteristics on an oscilloscope or using an optional data acquisition module.

An extensive 100-page User’s Guide is provided detailing the operation of Mr. SQUID® and includes many experiments suitable for laboratory experiment courses. Mr. SQUID® demonstrates the principles of superconductive electronics with the addition of only liquid nitrogen and either an oscilloscope or an optional data acquisition module.

MS-OSC Microwave Oscillator

The Model MS-OSC Mr. SQUID Oscillator accessory for STAR Cryoelectronics’ Mr. SQUID Educational Demonstration System is a 44 GHz microwave oscillator for the Mr. SQUID Shapiro step experiment. The Mr. SQUID Oscillator accessory is compatible with all STAR Cryoelectronics’ Mr. SQUID probes and MS-EB03 control electronics.

MS-FLL Flux-Locked-Loop

The Model MS-FLL Mr. SQUID Flux-Locked Loop accessory for STAR Cryoelectronics’ Mr. SQUID Educational Demonstration System is used to operate Mr. SQUID in a locked-loop feedback mode. The Mr. SQUID FLL accessory is compatible with all STAR Cryoelectronics’ Mr. SQUID probes and MS-EB03 control electronics (Rev. B or later).

MS-DAQ Data Acquisition and Control Software

The Model MS-DAQ14 Mr. SQUID Digitizer accessory for STAR Cryoelectronics’ Mr. SQUID Educational Demonstration System enables students to digitize, display, and capture Mr. SQUID current-voltage (V-I) and voltage-flux (V-) characteristics on a Windows-based PC via a USB 2.0 interface. The digitizer is bus powered and based on a National Instruments 14-bit data acquisition device with 48 kS/s maximum sampling rate. A higher resolution model (MS-DAQ16 with 16-bits, 250 kS/s) is available for more demanding measurements applications. The Mr. SQUID Digitizer accessory is compatible with all STAR Cryoelectronics’ Mr. SQUID probes and MS-EB03 control electronics.
