Welcome to the GammaRay 2018 Workshop page of the GammaWiki web. Here you will find information on the upcoming GammaRay 2018 workshop on gamma spectrometry. We hope to see you there and in particular we encourage students and younger scientists to attend. Information and material from previous workshops can be found here.

Registration form

The registration form for workshop participants is available here. Please fill in and send. Deadline for registration is 1 September 2018, but we would appreciate if you expressed your intention to participate as soon as you can.

Get-together on Monday evening

In the evening of Monday the 24th, at 19:30 when most of you have arrived and settled in (and possibly been to the local swimmingpool at Laugardalslaug), we kindly offer you to a casual get-together where we have the chance to meet and have some drinks and snacks.

The address is Laugarnesvegur 57, the home of one of IRSA‘s employees. It is a short walk from Grand Hotel, and for those staying further away, bus no. 12 stops immediately in front of the house (bus stop Laugarnesvegur/Borgartún).

We sincerely hope to see you all there.

Seminar agenda

The workshop agenda can be found here.

Time and place

The GammaRay 2018 workshop will be held in Reykjavik, Iceland 25.-26. September 2018 at CenterHotel Miðgarður.

The venue for the workshop is CenterHotel Miðgarður. This is about 1,4 Km from Grand Hotel, where most of you are staying (check this map); a refreshing 15-minute walk in direction downtown. This is two bus stops, one could theoretically also take a bus or taxi in case of really horrible weather. You can, in fact, rent bikes at Grand Hotel, which is of course the best means of transport in central Reykjavik. WOW also has a bike rental stand close to the hotel.

Those of you who do not stay at Grand Hotel, don't worry - CenterHotel Miðgarður is located directly at Hlemmur; the main bus hub of Reykjavik so getting to and from the workshop venue should be as easy as it gets.

Seminar cost

No seminar fee will be charged.

General travel information
