1.0 Standard Equipment and Services1.1 Control Console

The standard control console is a touch screendisplay system. An optional desktop PC controlconsole is available (see section 4.6).

1.2 X-ray Head Low Leakage (0.1%)

1.3 Modulator/Power Distribution CabinetExternal signal interface

1.4 Temperature Control Unit (TCU)The TCU is used to keep the system components ata nominal 30˚C (86˚F). It is available in high voltageand low voltage configurations for environmentsranging from -40/+55˚C (-40/131˚F), condensing.

1.5 Standard Spare Parts KitThe standard spare parts kit includes over 40 itemssuch as PC boards and individual components.

1.6 Interconnecting Cables (X-ray Head to Modulator.Modulator to Console) and Hoses (TCU to X-rayHead) Included. Lengths up to 100 meters.

1.7 Manuals and Data BooksTwo sets of operator and maintenance manuals anddata books are included in English.

1.8 Installation Supervision and Start-up Assistance

1.9 Varian’s Standard Warranty

2.0 Performance2.1 X-ray Beam Quality

The X-ray beamquality is specifiedusing Half ValueLayer (HVL) steel.This corresponds tothe nominal X-rayenergy shown inTable 1. These HVL numbers are derived from a compilation of broad beam data measurements.

2.2 X-ray Beam Dose Rate* (10 cm x 10 cm field)The maximum continuous dose rate at 1 meter islisted in Table 1. (Without flattening filter.)* Dose rate is reduced with flattening filter.

2.3 X-ray Field SizeA 30˚ cone or 22.5˚ square defines the field. Alsosee section 4.1.

2.4 X-ray Beam Focal Spot SizeThe focal spot size does not exceed 2.0 mm indiameter.

2.5 X-ray Beam SymmetryThe beam asymmetry does not exceed 5% at ±7.5˚off the central axis for all energies.

2.6 Radiographic QualityThe Linatron-M system will demonstrate at leastASTM E 94 1-2T, or equivalent, sensitivity over theranges given in Table 2 using film detection.

2.7 Standard Leakage RadiationThe leakage radiation is specified along thehorizontal axis at 1 meter from the beamcenterline at angles 60˚ and greater, outside theprimary beam. The values in Table 3 are afraction of the primary beam central axis doserate measured with a 10 cm x 10 cm collimator.Leakage is taken with the primary beamcompletely blocked. See section 4.2 for lowerleakage options.

3.0 Customer Facility Requirements3.1 Electrical Requirements

3.1.1 The Linatron-M operates from a single 15-kVA 50/60 Hz power source. Two voltageranges are available.3.1.1.1 Low Voltage Option

208 VAC, 3 phase, 3 or 4 wire plusground, 60 Amp minimum surgeper leg. ±10% voltage regulation isrequired.

3.1.1.2 High Voltage Option400 VAC, 3 phase, 4 wire plusground, 40 Amp minimum surgeper leg. ±10% voltage regulation isrequired.

3.1.2 The TCU is connected to a separate 13-kVApower source. Models are available that canoperate on a line voltage of 220 VAC and400 VAC, at 50 Hz; or 220 VAC and 480VAC, at 60 Hz. A separate 10-kVA powersource may be required for the in-line heaterpackage.

3.2 Operating Requirement

3.2.1 Indoor RequirementThe operatingenvironment forcontrol console andmodulator must bebetween 4˚C (39˚F)and 35˚C (95˚F),with 90% maximumrelative humidity(non-condensing).

3.2.2 Outdoor RequirementThe available temperature range for X-rayhead/RF unit is dependent on the TCU and thermal insulation blanket. The rangecan be absorbed as -40/+55˚C (-40/131˚F),condensing.

3.2.3 VentilationThe approximate heat given to room airfrom each component with system operatingat full power is given below:X-ray Head/RF Unit: 1.0 kWModulator Cabinet: 2.0 kWTemperature Control Unit: 6.0-12.0 kWTouchscreen Control Console: Negligible

4.0 Optional Equipment4.1 Custom Beam Collimation

Nonstandard field sizes are available per customer’srequirements. A motorized collimator is alsoavailable to quickly change the beam collimation.

4.2 Lower Leakage Options are listed in Table 4.

4.3 Voltage RegulatorRecommended for installations where line powershort-term fluctuations are greater than ±5%. Astep-up or step-down transformer can also beordered to adapt a non-standard voltage source foruse with the Linatron or TCU. The regulator isCE and UL approved.
