Proton Accelerator Facility

TAEK PROTON ACCELERATOR FACILITY

General Information

Strategically the most important goal of TAEK is to enhance the use of products of nuclear technology by acquiring it for the utmost benefits of Turkey. One of the objectives of TAEK in reaching this goal is to establish the required nuclear technology infrastructure in Turkey in parallel with the national priorities.  

The accelerator technology is one of the significant generic technologies, which entered to the service of humankind in 20th century. Being a generic technology, accelerators have a leading role in various fields of science and technology. Today accelerators play a central role in scientific studies ranging from biology to health, from materials science to metallurgy, from fundamental particles to universe. In countries advanced in science and technology, there are about 15,000 accelerators with different technological specifications serving for different purposes.

According to a document of International Atomic Energy Agency (IAEA) published in 2006, there are 262 cyclotron type accelerators in 39 countries for the production of radioisotopes. Today, the number of this type of accelerators is estimated to be around 350.  The number of cyclotrons used for radioisotope production has increased by 7% between 2002 and 2006. The number of cyclotrons is still increasing fast today. The United States of America (70), Japan (36) and Germany (23) rank in the top three countries that have the highest number of cyclotrons.

By the commissioning of TAEK Proton Accelerator Facility (TAEK-PAF), an infrastructure for accelerator technology with an integral type of facility that was designed for radioisotope and radiopharmaceutical production, quality control and research and development will have been established in Turkey for the first time. Eventually various institutions in our country in the field of medicine and research will benefit from this Facility, which is a unique type of its kind.

Scope of the Project

TAEK-PAF is established in Sarayköy Nuclear Research and Training Center of TAEK in Ankara. The project scope includes the construction of the building housing cyclotron type of accelerator and target systems, radiopharmaceutical production and quality control laboratories; construction of supporting buildings; environmental arrangements and construction of  infrastructure; supply, installation and tests of equipment and systems; personnel training.

First concrete was poured in February 24, 2010 and the construction of the Facility was completed in December 10, 2010. Installation and commissioning tests of cyclotron and target systems, equipment for radiopharmaceutical production and quality control laboratories are planned to be completed by August 2011. The radiopharmaceutical production at TAEK-PHT is expected to start in 2012.

CYCLONE-30 Cyclotron Type Accelerator System

 Objective of TAEK-PAF

TAEK-PAF is established to produce iodine-123, flourine-18, indium-111, gallium-67 and thallium-201 used for diagnosis of organs and several diseases such as cancer, neurological diseases, physiology of brain and its pathology, coronary diseases and heart imaging. The production of radiopharmaceuticals, quality control of products and distribution of products as patient dose will be conducted at the Facility. Besides, research and training activities in nuclear field will be undertaken at TAEK-PAF.

Technical Specification of Proton Accelerator Facility
The cyclotron accelerator system (Cyclone-30) has the state-of-art technological features of its kind. The proton beam energy is variable and the maximum energy is 30 MeV. The total beam current on target is also variable and the maximum current achievable is 1200 µA. The cyclotron designed by Ion Beam Application Company (IBA) is the first of a kind of its family of production with respect to the ion source yielding the aforementioned maximum total proton current. The cyclotron system has four beam lines; three of them will be used for radioisotope production and one for research and training.
