Announcement from ACMCC

Instruments shall be shipped and have reached the TC Unit before the first day of the workshop. During the first 10 days, they are installed by the ACMCC personnel and then operated in ambient air for stabilization purposes. Calibrations are then mainly conducted during the second week and beginning of the third one. A series of technical and scientific meetings is also planned at the TC unit during the workshops, typically during a 3-day period during the second or third week of the workshop.

Quadrupole ACSM : 12.09 - 30.09.2022

ACTRIS Intercomparison workshop of chemical ionization mass spectrometry, September 2022 at TROPOS

Dear ACTRIS Community,

This message is meant for all of you working with chemical ionization mass spectrometry.

We warmly invite you to take part in an intercomparison workshop for chemical ionization mass spectrometry to measure condensable vapors in September 2022, Leipzig, Germany. More information can be found in the attached document and below.

Please indicate your interest in participating in the workshop by 1st June 2022 via contacting us at We are also happy to answer any questions you may have.

Thank you very much!

EMC2: Opportunity to access EMC2 services through RADIATE Transnational Access (TA)

EMC2: Opportunity to access EMC2 services through RADIATE Transnational Access (TA)

LABEC, the INFN accelerator laboratory hosting the EMC2 unit, is participating in a European research infrastructure of ion beam facilities, RADIATE (, that currently offers transnational access (TA) to the external-beam PIXE-PIGE facility for atmospheric aerosol sample analysis to external users.

Member of ACTRIS can benefit of this opportunity for high-sensitivity and high-throughput elemental analysis of atmospheric aerosols collected on daily, hourly and size-segregated (e.g. impactor) samples, using Ion Beam Analysis techniques, typically PIXE and PIGE with 3 MeV proton beams and exploiting a dedicated detection set-up made by an array of Silicon Drift Detectors for X-ray spectroscopy. Given the pandemic situation hands-off experiments are welcomed: the user sends the aerosol samples, we will analyse them and then we will send them back.

The users have to submit a proposal to RADIATE’s proposal submission system, RADIATE GATE (https:// Check this presentation as a guideline.

Access is granted free of charge to positively evaluated proposals. Download the proposal template to prepare your proposal.

Information on how to submit a measurement proposal to RADIATE TA can be found at the following website:

After the beam time at LABEC , once the measurements are finished, you will have to submit an experimental report in RADIATE GATE.

It is suggested that you contact Massimo Chiari ( before submitting a proposal for advice on the beam analysis method and requested hours that are most appropriate, and for support in proposal submission.
