Varian Clinac iX (6 MV / 18 MV dual-energy)
Family: Varian Clinac iX · Modality: Linear Accelerator (Rad Onc)
Dual-photon-energy Clinac iX with 6 MV and 18 MV X-ray beams. Higher high-energy photon than the 15 MV sibling — historically preferred for deep pelvic targets before IMRT/VMAT made high-energy beams less important. Very large installed base, same refurb parts pool as 15 MV variant.
Variant-specific considerations
- 6/18 MV dual photon, typical electron menu 4/6/9/12/15/18 MeV
- Millennium 120 MLC
- Same OBI, same service footprint as 15 MV variant
- Shielding implications: 18 MV neutron activation is a consideration for facility design
Parts
Klystron (HD), waveguide, Millennium 120 MLC, OBI, electron applicators — most parts interchangeable with 6/15 MV variant except high-energy-specific tuning.
