Role of the Linear Accelerator (LINAC) in Security and Cargo Inspection – Part I

By:  Samy Hanna, PhD, PE. - Consultant Many ports around the world rely on X-ray scanners to inspect cargo for nuclear materials or weapons and prevent contraband from entering their countries. Conventionally, these have been gamma-ray scanners based on radioactive isotopes such as cobalt-60 or the common DC X-ray tubes. In spite of the recent advancement in X-ray tube technology, they are still ...

Role of the Linear Accelerator (LINAC) in Cancer Radiation Therapy

linac_se
By:  Samy Hanna, PhD, PE. - Consultant Radiation therapy or radiotherapy (RT) describes the clinical process that uses ionizing radiation to kill cancerous cells. It is one of the major medical modalities used in treating cancer. Other widely used cancer treating modalities are surgery and chemotherapy. Actually, more than half of all cancer patients receive radiotherapy, either alone or in com...

Manufacturing Techniques of a Linear Accelerator (LINAC)

By:  Samy Hanna, PhD, PE. - Consultant Precise operations of medical and industrial linear accelerators impose certain demands on both materials used and fabrication techniques utilized. They both need to be compatible with ultra-high vacuum, high-power RF, and the presence of particle beams. In this Linear Accelerator Blog Post, I will briefly discuss materials compatible with these demands an...

STRINGERS & PIPES

Recall the blistering or ruptures that can be experienced when you braze non-OFE Copper in Hydrogen (see Blog Post October 7, 2009).  As a follow-up post, we want to briefly discuss “stringers.”  Stringers are actual holes or leaks paths in the material that follow grain directions and are intrinsic to many grades of materials that are used in vacuum applications.  (more…)
