| TU2AO06 | Accelerator Control Class for Graduate Students in SOKENDAI, KEK | 335 |
|
||
|
The Graduate University for Advanced Studies, known as SOKENDAI, provides educational opportunities for graduate students in collaboration with national research institutions in Japan. KEK is one of the institutes, and has a program "Accelerator Science". Since 2019, we started two classes: lectures "Introduction to accelerator control system" for one semester, and a two-day seminar "Control of distributed devices for large systems". The former consists of 12 lectures on various topics of accelerator controls by teachers, followed by a presentation day by students. The latter consists of lecture and hands-on, which enables students to practice EPICS with Raspberry-pi based devices. In the paper, status of accelerator control classes are reported.

| TUPDP046 | Beam Operation for Particle Physics and Photon Science with Pulse-to-Pulse Modulation at KEK Injector Linac | 627 |
|
||
| The electron and positron accelerator complex at KEK offers unique experimental opportunities in the fields of elementary particle physics with SuperKEKB collider and photon science with two light sources. In order to maximize the experimental performances at those facilities the injector LINAC employs pulse-to-pulse modulation at 50 Hz, injecting beams with diverse properties. The event-based control system effectively manages different beam configurations. This injection scheme was initially designed 15 years ago and has been in full operation since 2019. Over the years, quite a few enhancements have been implemented. As the event-based controls are tightly coupled with microwave systems, machine protection systems and so on, their modifications require meticulous planning. However, the diverse requirements from particle physics and photon science, stemming from the distinct nature of those experiments, often necessitate patient negotiation to meet the demands of both fields. This presentation discusses those operational aspects of the multidisciplinary facility. | ||

| TUPDP047 | Development of Operator Interface Using Angular at the KEK e⁻/e⁺ Injector Linac | 631 |
|
||
| At the KEK e⁻/e⁺ injector linac, the first electronic operation logbook system was developed using a relational database in 1995. This logbook system has the capability to automatically record detailed operational status changes. In addition, operators can manually input detailed information about operational problems, which is helpful for future troubleshooting. In 2010, the logbook system was improved with the implementation of a redundant database, an Adobe Flash based frontend, and an image file handling feature. In 2011, the CSS archiver system with PostgreSQL and a new web-based archiver viewer utilizing Adobe Flash. However, with the discontinuation of Adobe Flash support at the end of 2020, it became necessary to develop a new frontend without Flash for both the operation logbook and archiver viewer systems. For this purpose, the authors adopted the Angular framework, which is widely used for building web applications using JavaScript. In this paper, we report the development of operator interfaces using Angular for the injector linac. | ||

| TUPDP048 | The Upgrade of Pulsed Magnet Control System Using PXIe Devices at KEK LINAC | 635 |
|
||
| In the KEK electron-positron injector LINAC, the pulsed magnet control system modulates the magnetic field at intervals of 20 ms, enabling simultaneous injection into four distinct target rings: 2.5 GeV PF, 6.5 GeV PF-AR, 4 GeV SuperKEKB LER, and 7 GeV SuperKEKB HER. This system operates based on a trigger signal delivered from the event timing system. Upon the receiving specified event code, the PXI DAC board outputs a waveform to the pulse driver, which consequently determines the current of the pulsed magnet. The combination of Windows 8.1 and LabVIEW was utilized to implement the control system since 2017. Nonetheless, due to the cessation of support for Windows 8.1, a system upgrade has become imperative. To address this, Linux has been selected as a suitable replacement for Windows and the EPICS driver for PXIe devices is thus required. This manuscript introduces the development of the novel Linux-based pulsed magnet control system. | ||

| FR2BCO05 | Magnet Information Management System Based on Web Application for the KEK e⁻/e⁺ Injector Linac | 1669 |
|
||
| The KEK injector linac provides e⁻/e⁺ beam to four independent storage rings and a positron damping ring. An accurate information management system of the accelerator components is very important since it is utilized for the beam tuning model. Especially, the incorrect magnet database may cause large deterioration in the quality of beam emittance. In KEK linac, a text-based database system has been used for the information management of magnet system in the long time. It comprises several independent text files which are master information to generate the EPICS database files and the other configuration files required for many linac control software. In this management scheme, it is not easy to access and update any information for the common user except control software expert. For this reason, a new web application-based magnet information management system was developed with the Angular and PHP framework. In the new system, the magnet information can be easily extracted and modified through any web browser for any user. In this paper, we report the new magnet information management system in detail. | ||
