Fluence to Dose Converter(TID)/Calculator(TNID) for and dedicated to ASIF (ASI Supported Irradiation Facilities) facilities

      for TNID Doses:

      for TID Doses:



  • The TNID dose is the total non-ionizing energy loss (NIEL) dose.
  • The TID dose is the total ionizing energy loss dose.
  • SEE (Single Event Effect)

The data generated by using the Calculator may be used by SR-NIEL developers for statistical purpose
