Knowing the transverse emittance through the acceleration cycle is imperative for efficient and successful operations. Relative measurements provide details of emittance growth problems while absolute measurements provide beam expectations upstream and downstream of the measurement. Both measurements are needed to fully understand the emittance as a whole. We learn the emittance by measuring...
Every RHIC physics store is analyzed, with key components updated
to a spreadsheet, to identify and monitor any improvements or degra-
dations in performance. With physics stores lasting between 50 min-
utes (optimal store length of 7.3 GeV Au in Run14) and 20 hours (store
length of 100 GeV Zr and Ru stores in Run18), manual analysis be-
comes a time consuming endeavor. To reduce the time...
A high machine availability is an important performance indicator for modern synchrotron light sources. To reach this goal of stabilizing operations by minimizing the occurrence and duration of downtime events, software tools play an important role. Reliable operation statistics are necessary, in addition to reliable tools for root-cause analysis and fault tracking. Here we describe how we do...
The most effective control system tools for operators are generally made by people who have experience in operations. At NSCL and FRIB, several operators are making their own CS-Studio content but are often limited by the signals available to them. One solution is to develop some degree of control system expertise within the operations group, enabling them to use the standard control system...
Most of the world's Accelerator Laboratory provides stable beam services through numerous control devices. In addition, EPICS (Experimental Physics and Industrial Control System) software is used to acquire the normal status and data of the device through a LAN (Local Area Network). The software that plays a central role in EPICS is an Input / Output Controller (IOC) and communicates directly...

Amount of instruments and devices these must be monitored and controlled...
At the WAO2014 I presented the Operations Simulator software I have developed. The simulator provides a training and familiarisation platform for operators, students or visitors. Initially the simulator was developed to work on the main control room PCs, but this tied the ‘users’ to the main control room. To remove the control room ties the Simulator software (EPICS IOC, Cothread, and...
The first section of the ESS Linac (Ion Source and LEBT) will be commissioned during summer 2018. We will present the first results and which lessons we learned in order to prepare for commissioning the rest of the machine and how to grow the operations team.
This paper first discusses the hardware and software structure of the Hefei Light Source control system. Based upon the Hefei Light Source control system, we developed a number of high level applications for machine commissioning and operation. This dissertation reports some critical applications, including the energy matching between the injector and the storage ring, lattice calibration and...
Not so many "entry level" operators, for example with one year of experience, have enough knowledges and skills for accelerator operator. Their supervisors require high level skills as ideal operator, whereas "entry level" operators have many things to understand, gain experience and so on, and have not enough time to study. In order to eliminate the distinction between them, optimization of...
In addition to shift work in the control room, the operators perform secondary activities in various specialist groups during their normal working hours.
Secondary occupation in the division Insertion Device
Outside of shift work, we are involved in the maintenance of the insertion device of SLS and SwissFEL. These maintenance can only take place in the machine shutdown, which becomes a...
Operations at National Synchrotron Light Source II (NSLS-II) require the coordination of many critical systems and subsystems. The majority of graphical user interfaces (GUIs) for these systems were developed individually as needed during the early stages of commissioning as the facility was coming online. As the NSLS-II has become an operational facility, however, ease of use has...
The Isotope Separator On Line Device (ISOLDE) can profit from up to 60% of the protons the Proton Synchrotron Booster (PSB) can deliver. The protons are essential, to deliver the wide range of isotopes required. The machine supervisor main task is to guide the beam through the different sections of the facility and deliver it to the users. The team utilizes a variety of tools to perform the...

American culture has accustomed us to working a third of a day for 5 out of 7 days. Certain times are preferred over others. Due to the fixed cost of cryogenic operations, running all day, every day is preferred for a given Run (ie the time between long maintenance periods). Staff load analysis recommends a crew of 2 Operators with a Crew Chief for oversight. How should the coverage be...
