ISU Microwave LINACS

 

TYPE: L and S band electron LINACS:  electron and bremsstrahlung radiation sources.IAC Microwave LINACS

Application: Sources of electrons, photons and neutrons for various irradiations and activation.

Availability: Schedule an accelerator here

Host Location: Idaho State University, Idaho Accelerator Laboratory, Pocatello, ID

Sponsor:  Internally managed and operated by ISU/IAC

Test Object Size: various depending on distance and dose rate, 1cm2 to 30 cm2

General Description: 

Pulsed traveling and standing wave LINACS, some with multiple beam ports and beam access into a separate shielded cell. The L-Band accelerator is the former Santa Barbra DoE operated short pulse machine.  Its energy range is from 1 MeV to 25 MeV with a pulse width from 60 pico seconds to 2.0 micro seconds.  It has a 90 degree bended line with slits for precise energy selection as well as a zero degree line.  The 25 MeV S-band accelerator is a general-purpose LINAC with a zero and 45 degree line. Maximum beam energy is ~ 25 MeV and minimum ~ 4 MeV.   We also have two 40 MeV S-band  accelerators for high power activations primarily used for isotope production.

ISU TriMeV

 

Type: Accelerator; electron and bremsstrahlung radiation source

Application: X rays for simulation of x-ray, and thermo-mechanical shock effects 

Availability: Schedule an accelerator here

Host Location: Idaho State University, Idaho Accelerator Laboratory, Pocatello, ID

Sponsor: ISU and Federal Agencies                Operator: ISU/IAC

Test Object Size: 5 cm2 to 3 m2

General Description: TriMeV is a  pulse power, high-voltage, single shot, and low-cost electron-beam/bremsstrahlung accelerator. TriMeV can be used to measure the response of electronics to pulsed, high-energy x rays. TriMeV can also generate an electron beam that can be propagated through a drift cell for measurements of thermo-structural response of materials to pulsed radiation.

Converter Design: ~360 µm Ta + ~5 mm Al

Bremsstrahlung End Point: 3.0 MeV

Maximum Dose Rate: > 1.5X1011 rad/s (CaF2) ~0.5” from end plate, > 4X1011 rad/s (CaF2) on end plate.

Pulse Width: Fixed at 20 ns FWHM

Rise Time: 2 ns

Instrument and Data Collection: There is a user screen room that contains 4 channels of Tektronix DPO 7054, 8 channels of Tektronix 5104, 4 channels of Tektronix 3034, and 8 channels Tektronix 2024.

Special Features and Requirements:

  • TriMeV is located in the large IAC high bay, light labs and offices are available.
  • The user screen room is ~ 100’ from the test cell.
  • All customers must follow IAC safety regulations

Typical Costs and Schedule Lead Times:  $282/hour with 42% indirect charge.  10 hour day minimum.  1 hour of research/engineering support charged per 5 hours of shot time.
