DAQ/FEE/Trigger for COMPASS beyond 2020 workshop
CTU FNSPE Prague
This workshop is focused on development needed for COMPASS beyond 2020. We will discuss required performance and architecture of FEE and DAQ components, unify serial interfaces and protocols, discuss trigger processor hardware, and distribution of workload. One of the topics will be also development of Si detector systems for polarized target. More info can be found at workshop web page

COMPASS future physics program
The M2 beam line at CERN is a unique hadron and muon facility. COMPASS has submitted a proposal requesting the extension of the COMPASS-II program in and beyond 2021. A Letter of Intent will be submitted by the end of 2017 suggesting a rich physics program to explore hadron structure using conventional meson beams, muon beams, and finally RF-separated hadron beams to enhance the fraction of beam kaons and anti-protons.

Proton radius measurement
The measurement of the proton radius is part of the proposal for the future COMPASS program. While continuing to use the DAQ and trigger system in the current way appears to be feasible, improving in particular the trigger is desirable to increase the number of recorded elastic events. I will present some ideas to achieve this, along with presenting the requirements to the COMPASS set-up for a successful measurement.

INFN Torino Electronics Service
Electronics Service of the Turin section of INFN (Electronics Laboratory) fulfills all the requests made by different physics research groups providing both design, systems realization and test capabilities of discrete electronics and microelectronics devices.
Design activities range from the very front-end electronics to the development of full read-out and data acquisition systems.
Microelectronics design is one of the main activity of the Laboratory for the development of full-custom ASICs circuits. The team of IC designers has a long experience in analogue, mixed-mode or digital IC design.
In addition the Electronics Laboratory provides design capabilities oriented to the implementation of Printed Circuit Boards (PCBs) and to digital programming techniques using Field Programmable Gate Arrays (FPGAs).
This presentation gives a very short overview of all this activities, focusing on revelant projects and recent developments.Speaker: Giulio Dellacasa (Universita e INFN Torino (IT)) -

Experience and developments in ASIC design at INFN Torino
The presentation will describe the ASIC design activities at INFN Torino, with special focus on the developments for hybrid and monolithic pixel detectors, for timing measurements and for high speed data transmission circuit. ASICs currently used in various applications (ALICE ITS, COMPASS RICH, GBT common interface and medical interface) will be described, togheter with the recent developments in timing applications and HL-LHC prototypes.

Current iFDAQ Software Status
The contribution presents development and recent status of the Data Acquisition Systems (DAQ) of the COMPASS experiment at CERN. It focuses especially on development and deployment of the new communication library DIALOG and DAQ Debugger for the error detection. The DIALOG library is a communication system both for distributed and mixed environments, it provides a network transparent inter-process communication layer. In general, state-of-the-art Data Acquisition Systems (DAQ) in high energy physics experiments must satisfy high requirements in terms of reliability, efficiency and data rate capability. In complex software, such as the DAQ, having thousands of lines of code, the debugging process is absolutely essential to reveal all software issues. The resultant DAQ stability is discussed at the end and comparison with previous years is given.

DAQ Software Interventions before 2018 Run
The preliminary schedule of DAQ changes before the Run 2018 has been already discussed and accepted. There are prepared two major interventions. The current DAQ is limited to event size up to 512 KB. First intervention gets rid of such event size restriction and provides with more general DAQ. Second intervention takes into account the integration of cross-point switch. It considers all aspects such as database, new slave control process and responsibilities of master process. Moreover, the contribution defines all allowed features in Topology GUI based on the current DAQ status from the user’s point of view. In the end, open questions rising from the cross-point switch integration are stated.

Command line interface
Having a graphical-only user interface to the DAQ has proven problematic in two matters: remote access and run control automation. This talk will address the current status of the command-line interface and describe how it solves these problems, including the “script mode“ feature introduced earlier this year. A short workshop session on how to write scripts against this interface will also take place during this talk. Finally, future plans will be discussed, especially the relationship of the command-line interface and the COMPASS API.

Support Tools
In our contribution, we present several tools that simplify work with data taking shifts at COMPASSS experiment at CERN. At first, we introduce online shift reservation tool. Administrator (or year coordinator) can use the tool to define list of shift for given data taking period. Members of the experiment use the tool to sign in for shifts according to their preferences. The tool automatically calculates served shifts for each institution, moreover concept of coefficients that rate different types of shifts (night, weekend) was introduced. In the second part of our talk, we present electronic checklist which would replace need to fill in paper forms. The shifter downloads form prepared by administrator into tablet, fills it in, and uploads the result. The application is able to work offline, moreover it verifies that all values are valid and within correct range. Both applications are prepared for deployment in the case they are approved.
