TUPV015 | EPICS Based High-Level Control System for ESS-ERIC Emittance Measurement Unit Device | software, controls, EPICS, hardware | 423 |
|
|||
For low energy linear accelerators, a typical method for measuring the transverse emittance consists in a slit and grid system. In ESS-ERIC* dedicated Emittance Measurement Units (EMUs) are used to calculate the transverse phase space (horizontal and vertical) and they are composed by a slit and grid system. This system let users reconstruct the distribution of particles in x and x’ (or y and y’), position and angle between particle trajectory and z axis, respectively. The EMU aims to measure the transverse emittance by sampling the transverse phase space. Considering control system aspect, a single EMU device is composed by different sub-systems (acquisition, motion, etc.). In this paper the software layer developed in EPICS** and realized to orchestrate the entire apparatus and control the different sub-systems will be described.

TUPV016 | Design and Development of the New Diagnostics Control System for the SPES Project at INFN-LNL | controls, diagnostics, hardware, EPICS | 428 |
|
|||
The need to get finer data to describe the beam is a relevant topic for all laboratories. For the SPES project at Laboratori Nazionali di Legnaro (LNL) a new diagnostic control system with more performing hardware, with respect to the one used in legacy accelerators based on Versabus Module Eurocard (VME) ADCs, has been developed. The new system uses a custom hardware to acquire signals in real time. These data and ancillary operations are managed by a control system based on the Experimental Physics and Industrial Control System (EPICS) standard and shown to users on a Control System Studio (CSS) graphical user interface. The new system improves the basic functionalities, current read-back over Beam Profilers (BP) and Faraday Cups (FC) and handlings control, with new features such as: multiple hardware gain levels selection, broken wires correction through polynomial interpolation and roto-translations taking into account alignment parameters. Another important feature, integrated with the usage of a python Finite State Machine (FSM), is the capability to control an emittance meter to quickly acquire data and calculate beam longitudinal phase space through the scubeex method. | |||

THPV037 | The Implementation of the Beam Profile Application for KOMAC Beam Emittance | EPICS, controls, linac, proton | 947 |
|
|||
Funding: This work was supported by the Ministry of Science, ICT & Future Planning of the Korean Government. Korea Multi-purpose Accelerator Complex(KOMAC) has been operating a 100 MeV proton linear accelerator that accelerates a beam using ion source, a radio frequency quadrupole(RFQ), 11 drift tube linac(DTL). And the accelerated protons are transported to target rooms that meets the conditions required by the users. It is important to figure out the beam profile of the proton linac to provide the proper beam condition to users. We installed 8 wire scanners to measure beam emittance of KOMAC at beam lines. And beam profile application to measure beam emittance has been implemented using EPICS and python. This paper will describe the implementation of the beam profile application for KOMAC beam emittance. |
