The Beijing Electron Positron Collider II (BEPCII) has achieved a series of achievements in high energy physics study. Along with the deepening of the research, more important physics is expected in higher energy region (>2.1 GeV). As the upper limit of BEPCII design energy is 2.1 GeV, an urgent upgrade is required for BEPCII. To achieve a higher luminosity at higher energy, the number of RF cavities is expected to be doubled. The baseline design which kept the survey of the North Collision Region (NCR) unchanged for the upgrade of BEPCII has been studied in previous work. In this paper, we show an alternative design that modifies the survey of NCR, but enables the online maintenance of both RF cavities in each ring of BEPCII. The dynamic aperture tracking result shows that the lattice could meet the injection requirement of BEPCII beam with reasonable margin.

There are substantial and growing gaps in cancer care for millions of people in Low- Middle- Income countries (LMICs) and for geographically remote settings in High-income countries (HICs), often indigenous populations. Assessing the cancer care shortfall led to understanding the essential gap, that of a radiation therapy machine that can reliably and effectively provide the appropriate first-rate cancer treatments within the challenging environments. More than 10,000 electron linear accelerators (linacs) are currently used worldwide to treat patients. However only 10% of patients in low-income and 40% in middle-income countries who need radiotherapy have access to it. The idea to address the need for a novel medical linac for challenging environments has led to the creation of the STELLA project (Smart Technology to Extend Lives with Linear Accelerators) project. STELLA is multidisciplinary international collaborative effort to design and develop an affordable and robust yet technically sophisticated linear accelerator-based radiation therapy treatment (RTT) in LMICs. Here we describe Project STELLA.
