History of the Conferences on

Chemistry and Physics at Low Temperatures


The CPLT conference series resulted from the merger of two long-standing international conferences: the Gordon Conference on the Chemistry and Physics of Matrix-Isolated Species and the International Conference on Low Temperature Chemistry

First conferences

The first united CPLT conference was organized by Mika Pettersson and Jan Lundell in 2013 in Jyväskylä, Finland. CPLT 2014 took place in Suzdal, Russia organized by Vladimir Feldman and Tatyana Shabatina.

Recent conferences

CPLT 2016 was organized by Joëlle Mascetti, Claudine Crépin, and Stéphane Coussan and took place in Biarritz, France. CPLT 2018 was organized by David Anderson and Robert Hinde in Laramie, Wyoming. The next CPLT will be held in Sapporo, Japan

Travel and accomodation

The CPLT Conference has been postponed to 3 - 8 July 2022 in Visegrád, Hungary, due to the COVID-19 outbreak.
Can I transfer my fee to the new dates?
Yes. The conference is postponed rather then cancelled so all paid registrations (including accomodation) and other fees via CPLT online registration page or by wire transfer are valid and automatically transferred for the 2022 conference with unchanged service content.

Yes. To transfer your registration to another person, please email CPLT2022 with the original delegate’s registration full name and provide us with the new delegate’s information.

Please ask your travel agent/airline and let them know you are cancelling or modifying your booking due to the postponement of CPLT conference in light of the COVID-19 pandemic. The responsibility for airfare bookings and refunds falls outside the scope of CPLT and will be dependent on the type of fare booked, the airline’s or agent’s own cancellation/rebooking policies regarding COVID-19, and any travel insurance coverage.

How to register?
Registration, travel and accomodation will be handled by the travel agent, ALTAGRA: cplt@altagra.hu. Do not book the hotel individually. Please contact the agent with questions not connected with the scientific program.

If your are unable to participate or to donate your registration at the new time, please notify us by sending an email to cplt@altagra.hu. Please note that cancellations can only be accepted in writing (cplt@altagra.hu) and are subject to the following conditions: Cancellations received before or on 16 May: 70 % refund will be made. Cancellations after 16 May will not result in a refund. Non-attendance to the event will not result in a refund.

The travel agent will accept credit cards via a secure homepage and bank transfers.
The location is easily accesible by car. The Conference provides transfer services for a fee on the first and last day of the conference between Budapest, Budapest Airport and Visegrád. See the details under Registration info. You can book your transfer during the registration process. Public transport is also possible: details below.

Frequent trains connect Budapest (Station Nyugati) to Nagymaros-Visegrád, from where a ferry crosses the Danube to the hotel. The same train line has direct trains to Bratislava and Prague every two hours from Nagymaros. Schedules and online tickets

There are riverboats (slow boat and express hydrofoil) taking the very scenic river route from downtown Budapest direct to Visegrád. See online schedules and book tickets.

Intercity buses also arrive directly to the hotel from the bus station at Újpest-Városkapu metro station. See online schedules Tickets are to be bought at the bus station.

Is there guarded parking?
Yes, provided by the hotel.

Oral contribution are expected by May 22, 2022.

Poster abstracts before June 6, 2022.

Late registration (at increased fee) is from June 1, 2022.

Are there reduced student options?
Yes, we arranged a budget hotel to be available nearby. Please contact cplt@altagra.hu.
Are there sponsorship opportunities for students?
The present support from the sponsors was already distributed to the original student applicants. We might find additional sponsors for students (not more than 50% reduction). Students might register here for this tentative support with a short motivation letter and recommendation from their advisor before February 20th. No payment should be made until the decision is received.
