Description

Varian Clinac Installation Data Package – Section One

This 85-page English Varian Medical Systems Installation Data Package (IDP), Section One provides detailed equipment and facility-planning information for Clinac 2000C/R, 2100C(/D), 2300C/D, 21EX and 23EX medical linear accelerators. The cover identifies this edition as English Version, May 2003.

This is not a routine operating manual or general service manual. It is an engineering and installation-planning package intended to help customers, architects, physicists, electrical engineers, mechanical engineers, structural engineers and contractors understand the facility requirements associated with installing the listed Varian Clinac systems.

The document combines architectural layouts, radiation-shielding reference tables, equipment clearances, base-frame and pit details, cable-routing requirements, electrical specifications, interconnection wiring, HVAC and plumbing data, cooling-system requirements, compressed-air specifications, equipment weights and dimensions, shipping information, pre-installation checklists and a supplemental Respiratory Gating installation section.

Clinac Models Covered by Section One

• Clinac 2000C/R
• Clinac 2100C(/D)
• Clinac 2300C/D
• Clinac 21EX
• Clinac 23EX

The document also contains references to Silhouette configurations where the same requirement or component information applies.

Important Clinac 6EX Scope Note

This Section One IDP is not the primary Installation Data Package for Clinac 6EX. The document itself explains that the Varian IDP is divided into multiple sections and identifies:

• Section 1: Clinac 2000C/R, 2100C(/D), 2300C/D, 21EX and 23EX
• Section 2: Clinac 600C(/D), 4EX and 6EX

Therefore buyers looking specifically for complete Clinac 6EX equipment/facility installation requirements should obtain Section Two rather than assuming the main Section One drawings apply to 6EX.

The final Respiratory Gating appendix does separately identify Clinac 600C/D and 6EX as machines that may be connected to the Varian Respiratory Gating system. That supplemental gating information does not convert the main Section One package into a complete 6EX IDP.

What the Installation Data Package Is For

The stated purpose of the IDP is to help customers, architects, engineers and contractors understand Varian equipment requirements and facility-design issues. The material is intended to support planning and construction-document preparation before delivery and installation of the accelerator.

Clinac Options and Configuration Planning

The Section One notes identify several options and configuration decisions that should be determined early in the facility-design process.

For the listed dual-energy Clinac systems, the manual identifies examples including:

• Clinac 2100C maximum photon-energy choices: 10, 15 or 18 MV

Radiation Shielding Reference

The IDP includes a dedicated Typical Room Shielding Tables section with planning data for the listed Clinac systems.

The shielding material includes:

• Typical primary-barrier thicknesses
• Typical secondary-barrier thicknesses
• Concrete shielding information
• Lead and steel shielding ratios
• Tenth Value Layer information versus X-ray energy
• Typical minimum Clinac room door shielding
• Neutron dose-equivalent information
• X-ray beam-quality reference values

The document discusses shielding for low- and dual-energy installations, maze design, shielded doors, duct penetrations and the additional neutron-shielding considerations associated with higher photon energies.

It repeatedly makes clear that final radiation-shielding adequacy is a site-specific matter to be determined and approved by the facility’s Physicist of Record. The drawings are marked Not For Construction and are provided as planning information rather than final site-specific structural or radiation-protection design documents.

Beamstopper and Primary Barrier Planning

The IDP explains the facility implications of an optional Clinac beamstopper. Where the applicable beamstopper is installed, it can reduce the need for increased primary barrier shielding, allowing the vault to be designed principally around secondary radiation shielding according to the applicable site design.

The document also warns that the beamstopper can interfere with some couch movements at certain gantry positions and may restrict installation of some accessory options.

Typical Treatment Room Layouts

The package contains detailed plan, section and isometric drawings showing a typical Clinac treatment room.

These drawings identify relationships among:

• Clinac Stand and Gantry
