This issue is an album of proton heavy ion tumor radiotherapy, which contains a review of foreign research progress in this field, domestic achievements in particle ray radiophysics research, including the calculation of radiation protection shield, quality control of active point scanning technology and the construction of medical particle synchrotron, as well as clinical experience in particle ray radiobiology research and carbon ion radiotherapy of head and neck tumors. This album provides readers with information on the latest progress of tumor particle radiotherapy at home and abroad, and also conforms to the rising upsurge of establishing particle tumor radiotherapy centers in China.

In 1946, American Wilson proposed proton therapy. In 1990, the first Loma Linda dedicated proton therapy center was built in the world. According to reports, in the 20 years between January 1990 and August 2013, the number of proton therapy rooms increased from 8 to 121, an annual growth rate of 13%, a total of 15 times. In September 2013, there were 43 proton (carbon ion-containing) treatment centers worldwide, accounting for 0.9% of the global conventional radiotherapy system. It is projected that there will be 1 500 particle therapy rooms worldwide by 2030.

Different from conventional medical equipment, the proton heavy ion therapy system has large equipment, long installation and debugging time, and high operation and maintenance cost^[1]In addition, a lot of manpower and material resources should be invested in the operation and management mode and supporting talent training reserves. This paper takes the proton and heavy ion equipment (IONTRIS system) of Shanghai Proton and Heavy Ion Hospital (SPHIC) as an example to introduce the operation status of its equipment.
