Product catalog summary

Introduction to Cryostats
CANBERRA offers a wide range of cryostat types, some specific to certain detectors, while others are versatile. Key types include:

Slimline: Standard for most detectors, except Si(Li) and Ultra-LEGe, featuring a cylindrical detector chamber for easy shielding and interfacing.
Flanged: Standard for Si(Li) and Ultra-LEGe detectors, with optional U-style fixed and swivel-head types.
Convertible: Modular design allowing field configuration changes, though more complex and costly with shorter service intervals.
Portable: The MAC and Big MAC are known for performance and reliability, available in Slimline and Flanged styles, with dual-port designs for extended LN2 holding time.
Retractable: Facilitates interfacing with vacuum chambers for low energy x-ray or beta experiments.
Electrically Cooled: Includes Cryolectric II, Cryo-Cycle™ Hybrid, and Cryo-Pulse™ 5, offering improved reliability and performance without LN2.
Ultra Low-Background (ULB): Designed for reduced background, with detailed specifications available in the ULB section.
ACT-II: Specifically for Actinide Lung Burden Systems, housing two Ge detectors in close proximity.

Options for Cryostats
Various standard and special order options are available, including:

Extended End Caps: Available in 51 mm increments up to 305 mm, providing unimpeded lengths beyond screw heads or preamp covers.
Remote Detector Chamber (RDC): Standard on ULB detectors, offering isolation via a 25.4 mm diameter neck, useful in high radiation fields.
Windows: Standard materials include Aluminum, Beryllium, and Composite Carbon, with optional polymer windows for very low energies.
Offset Neck Dewar: The D-30/OS Dewar features an offset port, available as an option for dipstick cryostats.
Special Dewar Sizes: Custom sizes and shapes available on special order, often required for specific applications.
