Practical information

- There are several convenient ways to get from Sofia Airport to the city center.

    public transport (both bus from T1 and T2 and metro from T2). Tickets can be purchased in the public transport itself with a credit card - you need to approach your credit card to the validation machines which are close to the entrance gates inside the bus. For the metro you approach you card at the access gates at the Metro station. Concerning the buses to and from the airport - there are regular checks so it is highly advisable to validate your ticket (i.e. your credit card) once you are in bus/tram. The ticket fee for a single ride is 1.60 BGN (~0.80 EUR).

    Taxi (Yellow! have contract with both terminals of Sofia airport, https://sofia-airport.eu/en/access/transportation/#by-taxi ), go directly to the operator terminal at the airport. The cost of the trip from the airport to the city center is of the order of 10-15 euro. 

    When choosing the public transport connections - Sofia public transport is relatively regular and convenient and the information is also shared with Google Maps services.

- The location of Faculty of Physics, Sofia University is

5 James Bourchier Blvd.,
1164 Sofia
Bulgaria

It is within a walking distance (10 min or less) from 

The entrance to the Faculty of Physics is from here:  https://maps.app.goo.gl/9B4wUtEnn5Q3xcaBA 
and when you enter the Sofia University campus (currently the entrance is under re-construction for the last ... 10 years) you need to go to the right to

      Search for Axion Dark Matter at LNF 55m A315 (Building A)

      Building A

      LOCATION: A315, Faculty of Physics, Sofia University

      The axion, a pseudoscalar particle originally introduced to solve the ‘’strong CP problem’’, is a well motivated dark-matter candidate with a mass lying in a broad range from peV to few meV. Axions clustered inside our galaxy may be observed by means of detectors called “haloscopes” consisting in a resonant cavity immersed in a static magnetic field that triggers the axion conversion to microwave photons.

      After a brief introduction to axion physics, I will present the status and perspectives for axion dark-matter searches at INFN. I’ll show the recent results of QUAX, an INFN experiment that operates two haloscopes at the national laboratories in Frascati and Legnaro, and discuss how to improve them using quantum sensing.

      Finally, I will present FLASH a large haloscope to be built by recycling a superconducting solenoid of 1.4 m radius, 2.2 m length and 1.1 T field at LNF. FLASH will probe axions with a mass around 1 micro-eV, as well as dark photons and high frequency gravitational waves. Recently, after the refurbishing of the cryogenic lines and of the control system, the magnet was powered with about 2700 ampere to generate, again after two decades, a 1.1 T field.
