GammaSkill 2023

Welcome to the GammaSkill 2023 page of the GammaWiki web. Here you will find information on the upcoming GammaSkill 2023 seminar and training event on gamma spectrometry that will be held in STUK, Vantaa, Finland, September 26-28, 2023. The GammaSkill 2023 seminar (September 27-28 2023) covers various aspects of gamma-ray spectrometry. The scope will be broad allowing a range of topics to be considered. The following areas could be included (but are not limited to):

Laboratory, in-situ and mobile measurements
Whole body measurements
Uncertainty calculations
Efficiency determination
Spectrum analysis and data management
Monte Carlo simulations
Nuclear forensics
Novel/new approaches
Applications

The GammaSkill 2023 training event (September 26) is aimed at those having already some experience or basic knowledge on gamma spectrometry. The participation of students and young scientists is highly welcome.

International experts will be invited to the seminar to give presentations on different aspects and new developments in gamma-ray spectrometry. Participants of the seminar are encouraged to give presentations on subjects of their choice, describing their applications of gamma-ray spectrometry and possible challenges encountered, new developments in detectors, electronics and data analysis.

Overview and background

This work is supported by the Nordic Nuclear Safety Research (NKS). GammaWiki is a resource webpage for Nordic users of gamma spectrometry. GammaWiki is a product of the NKS GammaSpec 2016 activity, which is an independent continuation of the GammaUser (2014), GammaTest (2013), GammaWorkshop (2011-2012), and GammaSem (2009) activities.

GammaSkill 2023 is the eleventh event in the series of gamma-ray spectrometry seminars. A page with links to individual information pages for previous seminars can be accessed here.

Registration

Please complete and send the completed Registration Form to Raisa Tiililä (raisa.tiilila@stuk.fi) by September 1, 2023. A Teams link will be sent in due time to those participants that cannot attend the seminar on site. The number of participants is limited to 100.

Programme

Here is the programme of the seminar and training event.

Travel and venue

The seminar will be organized by STUK. See instructions how to go from Helsinki-Vantaa airport to STUK. STUK has also issued the Booklet "How to arrive to STUK?". Please remember to bring your passport or ID card when entering STUK.

Accommodation: Group reservation in the Original Sokos Hotel Vantaa has been made by STUK. Everyone reserves and pays the room by her-/himself to the hotel. The reservation code is Gammaskil, see the registration form. See also list of some other hotels with itinerary and timetable suggestions. The organizers recommend booking the hotel as soon as possible.

Arrangement of the seminar and the training event

The seminar and training event will be held in STUK’s auditorium. A tour of STUK’s labs will be organized during the seminar.

Name, organization, and e-mail address of the participants will be given only to the participants (if you accept it).

A seminar dinner will be arranged in the Finnish Science Centre Heureka, which is located around 1 km from STUK and close to Hotel Vantaa.

There is no seminar fee.

Presentations at the seminar and material

The participants are encouraged to give presentations on subjects of their choice (15-20 min). We recommend attendees also to give “spontaneous” short presentations (5-10 min) on their work, see presentations of previous seminars.

We recommend that presenters send their presentations no later than September 18 2023 to Raisa Tiililä (see registration form).

All presentations will be put to the GammaWiki site after the seminar.
