Preliminary Specifications
1.0Performance
1.1
X-ray Beam Energy
The nominal peak beam energies are 9 Mev and 15MeV.
1.2
X-ray Beam Dose Rate
The dose rate is specified at one meter from the target,on the central axis, for one minute (Gy/min-m):9 MeV15 MeV12-36 Gy/min-m40-120 Gy/min-m1.3
X-ray Field Size
Beam and field size are based on the collimatorspecified by the customer.
1.4
X-ray Beam Flatness
Dose rate flatness as a percentage of the central axismeasured at ±6º off the central axis.9 MeV15 MeV55%45%1.5
X-ray Beam Symmetry
The beam asymmetry does not exceed 5% at ±6°offthe central axis in the vertical direction.
1.6
X-ray Beam Stability
Dose variation is within ±10% after the first 10seconds of beam on time. Use of reference detectorrecommended.
1.7
X-ray Beam Focal Spot Size
The focal spot size does not exceed 3.0 mm in
diameter for both energies. Consult factory for smallerspot size requirements.
1.8
Radiographic Quality
The system will demonstrate at least ASTM E 94-4 1-2T, or equivalent, sensitivity in steel at:9 MeV15 MeV76 mm (3\") to 254 mm (10\") to 254 mm (10\")460 mm (18\")Specifications subject to change without notice.

2.2
Leakage Radiation
Average leakage radiation over 100 cm2at 1 meterfrom the target outside of the primary beam will notexceed 0.1% of the central axis dose rate.
The K15 high-energy photons produce significantneutron radiation. This neutron production must beconsidered in plant building design. Special K15shielding limits the neutron leakage to approximately0.1% rem/X-ray rad in the forward cone from ±60°to±90°, and 0.01 rem/X-ray rad in all other directionsoutside the primary beam.2.3
Cabinet Enclosures
All system components including the X-ray head,modulator cabinet, and the temperature control unitare contained within grounded metal enclosures.

Indoor Service
The room temperature for all equipment (exceptTCU) must be between 5°C (41°F) and 35°C(95ºF) with maximum RH of 90% (non-condensing).
The standard Temperature Control Unit mayoperate inside or outside at temperatures from -10°to +40°C. A low temperature option allowsoperation to -40°C.
