About MaCS


The Microscopy and Characterization Suite (MaCS) is a state-of-the-art materials characterization laboratory that provides cross-cutting capabilities that support the Center for Advanced Energy Studies’ (CAES) mission in multiple initiative areas.  MaCS is largely made possible through its partnership with the Nuclear Science User Facilities (NSUF) (formerly Advanced Test Reactor National Scientific User Facility).

MaCS is complementary to the Boise State Center for Materials Characterization (BSCMC) that was established by the Idaho State Board of Education in August 2006 to provide a state-of-the-art characterization facility in order to attract more students into science and engineering careers, to improve science and engineering education at the undergraduate and graduate levels, and to foster leading research and interaction with local industry.

Collectively, MaCS and BSCMC provide the organization and infrastructure to make various materials characterization tools available for research, academia, and regional companies.

MaCS Operating Envelope


Nonradioactive Samples

  • Equipment: All imaging instruments and sample prep equipment may be used in MaCS for nonradioactive materials.
  • All imaging and sample prep activities shall be performed in accordance with CAES Operating Procedures.

Radioactive Samples

Materials: Radioactive material requests are evaluated as they are made, with consideration given to 1) whether the cumulative CAES inventory limit will be exceeded and 2) changing the CAES operating envelope for radiological materials.

The current rad operating envelope includes depleted uranium, solid activated ceramics, and fixed radiation sources. Depleted uranium may be in solid forms. Fixed radiation sources include activated metals: solid, non-dispersible, smearably clean (i.e., considered to be free of removable radioactive contamination) samples of activated metal and solid ceramic materials that are prepared to minimize sample mass and have a gamma dose rate of less than 70 millirem per hour at 30 centimeters are generally acceptable for analysis and testing in CAES.

  • Sample Receipt: Only clean samples will be delivered to CAES for analysis (< 70 dpm/100 cm2 ßγ and 7 dpm/100cm2 α).
  • Sample Preparation: Minor sample “touch-up” is the only sample prep activity allowed for radioactive samples. Touch-up shall be performed in accordance with CAES Operating Procedures, with each activity planned and approved on a project-by-project basis. Some nuclides may prove to be unacceptable for sample preparation until Phase 2. This reinforces the need to fully vet sample prep activities in the service request step of the process.
  • Equipment: All imaging equipment may be used for radiological sample analysis.

MaCS Training Requirements


All training is completed using the CAES Training Access Management System (TAMS). There are 2 training sections for MaCS:

  • If you are a non-rad or rad sample user complete section A.
  • If you are a long-term MaCS user (at CAES > 4 weeks/year) complete section A & B.

MaCS Training Sections

A. Training for Non-Rad and Rad Sample Users
  1. Complete the MaCS Rad Worker Training (TAMS, under MaCS)
    1. Rad Primer and Lab Orientation
    2. Area and Contamination Surveys (RSP-006)
  2. Read the Generic Instrument Protocol (RSP-001)
  3. Read Instrument Rad Protocols if applicable.
C. Training for Long-Term MaCS Users
  1. Complete training A.
  2. Complete the Facility Orientation (TAMS)
  3. Complete the Core Lab Training (TAMS)

The MaCS lab is a radiological laboratory that requires a dosimeter to be worn at all times, therefore radiological and non radiological MaCS workers must complete Idaho State University (ISU) radiological training located in the CAES Training Access Management Systems (TAMS).

Dress Code for MaCS

Researchers must wear:

  1. Shoes covering their entire foot
    1. No sandals, open toe shoes, or slipper type shoes
  2. Long pants or long skirts (Long: cover your ankle)
    1. No shorts, capris, or skirts
  3. Consider wearing cotton clothing in the winter months.
    1. Fleece and polyester cause false radon reads.

No food, drink, gum, mints, etc. in MaCS.
