EGANFEE synergy Working Group

PROMETEO Workshop on Front-End Electronics for gamma and complementary detector systems17-18 November 2011I IFIC – Valencia (Spain)

Coordination and synergy-building in the European Complementary

Detectors community

EGAN network tasks in the new ENSAR proposal


A bit of history:

The Ancillary / Complementary detector community wasone of the first to have a coordination group and EU funds for coordination and synergy building during EUROBALL period.

1994 – 1996 Conveners: Arne Johson and Örjan Skeppstedt Early meetings to create synergies among groups designing ancillary detectors for EUROBALL

1996 – 2003 Convener: Hubert Grawe Publication of the EUROBALL Ancillary Detectors booklet

2003 – 2004 Convener: Andres Gadea

Several Ancillary detectors included in the GammaPool

Inside the AGATA project: 2003 – 2010 W.G. Chairperson Andres Gadea2010 – present W.G. Chairperson Enrico Farnea


Current situation

• New RIB facilities require the development of experimental techniques and detectors

• design and construction or upgrade of complementary instrumentation

Synergy building and coordination in the community is essential and EGAN is an appropriate forum to create synergies among the groups developing complementary instrumentation

• Several arrays are active in our community (AGATA, EXOGAM, MINIBALL, GammaPool ones, etc … and their scientific production is mainly due to their coupling with ancillary detectors

• New large Ge -arrays are being build (AGATA) or upgraded (EXOGAM2) and several others are active in our community (also those related to the GammaPool (GALILEO))


Purpose:• ensure the maximum compatibility and versatility• minimizing the impact of ancillary detectors on

the performances of large Ge arrays• coordination in the construction and upgrade of

ancillary devices will allow:– the integration of the data acquisition and

electronics, – the integration of the mechanics (mechanical design

compatibility) – collaboration on the Monte-Carlo simulations of the

physics cases.


EGAN (ENSAR) TASK 2:Coordination on Ancillary Instrumentation

Subtasks as activity of Working Groups• Subtask 1: Activity of WG1: Co-operation on the

use, design and construction of ancillary detectors to improve the performance and compatibility of the devices.

• Subtask 2: Activity of WG2: Co-operation on designing and building the electronics and data acquisition and on the mechanical integration.

• Subtask 3: Activity of WG3: Exchange of information on the development of simulation tools.


Idea behind the subtasks: • 1) exchange of information between the groups involved in

the design and construction of ancillary detectors: to optimize the use of present resources and to improve the performance and compatibility of devices presently in the R&D phase.

• 2) exchange of information between groups responsible of the electronics, data acquisition coordination for the construction of common component. Exchange of information for mechanical integration and mechanical compatibility.

• 3) exchange of information between groups working on the development of simulation tools for the optimization of the detector design.


Detectors for new generation RIB facilities

Light Charged Particle detectors, Neutron detectors, Position Sensitive Heavy Ions detectors, Recoil detectors and binary reaction product detectors, Time measurement RDDS devices, Fast electronic timing detectors, High Energy Gamma detectors, Tagging detectors, Conversion electron filters and detectors .. etc…

Goal is to Disseminate Information onavailability and capabilities of detectors

and on new tools of simulation


Subtask 2: Activity of WG2: Co-operation on designing and building the electronics and data acquisition

• Interfacing analogue electronics with the Digital electronics arrays

• Development of digital electronics• High analogue/digital channel densities

(ASICS)• Participation in the trigger decision trees

Suggestion are welcome


On behalf of the European Gamma and Ancillary Detector Network, I wouldlike to invite PhD students and young researchers to attend the

EGAN school to be held at the University of Liverpool from 5th to 9thDecember 2011.

The aim of the school is to provide training and hands on experience inthe use of state of the art gamma-ray detector systems. The workshop

will focus on the use of highly segmented germanium detector systems,pulse shape analysis and the analysis of data from the AGATA spectrometer

Next EGAN Working Group Meeting:Together with the EGAN Workshop next year

Thank you
