THE ROLAND MAZE PROJECT - SCHOOL-BASED EXTENSIVE AIR SHOWER NETWORK

Schematic view of a single station

The idea of the whole network



The main scientific goals of the experiment are: * studies of CR spectrum in the energy range 1E18 - 1E19 eV, * studies of EAS in the knee region * monitoring single muon rate (space weather and atmospheric effects).

Educational impact:●introduction of modern physics to young enthusiasts,●contact with modern technologies (both teachers and students),

Educational impact:●introduction of modern physics to young enthusiasts,●contact with modern technologies (both teachers and students),●a way to get financial support for the Project.



The main scientific goal of the project are studiesof extremely high energy cosmic rays.

There are above 30 high schools in Lodz involvedin the Project.

UHE CR Events would hit detectors in a few schools.



Examples of simulated events.

Trigger conditions for UHE registrations:

1. min. 2 (out of 4) detectors hit in one unit2. min. 3 units fulfil condition 1.



Simulated 1 year of registration above 1018 eV

We expect about 400 EAS per year to be registered.(~1 per day)

For 30 units (schools):



Simulated showers and their localizations

For 30 units (schools):distributions of 500 EAS for different primary energies

The 4 detectors array in each school would register showers in the knee region with rate ~1/minute.

One can study:●shape of energy spectrum,●angular distribution,●anizotropy (celestial and galactic coordinates),●decoherence curve (repeating Maze's experiment).



Recording single detector counting rate allows for studies of:

●correlations with activity of the Sun and geomagnetic events (space weather),●the state of atmosphere, ●atmospheric effects (e.g. electric field, thunderstorm clouds),●correlation with temperature and atmospheric pressure.



Educational impact: ●young enthusiasts in the Lab



Educational impact: ●a way to get financial support for the Project

The Project is planned to include about 30 schools.Now we have about 150 students interested in the Project. We organized them in several groups.In 2004 the first stage: 10 schools.

We received about 60-67K Euro for 2004 from Authorities of the City of Lodz via Department of Education of the City Council.48-53 K Euro for materials, rest for education and training.

We found a lot of problems to use public money for our project: tenders, non-standard use of funds etc.


Now, many problems are solved, but the financial year is about to finish.(not all of expected funds can be used, some are still not available).



GPS: Motorola M12+Timing with Oncore Timing2000 antenna (135 Euro/item)(1PPS signal with accuracy better than 10 ns)



Detector:●1cm thick plastic scintillator●WSLE fibres●1 photomultiplier per 1 m2



2 tiles 10cm x 12cm x 0.5cm made in Protvinoform 1cm thick detector.We register each muon passing through detector.


Hands on CERN events in Lodz

In 2004 we had 2 events of HoC.Each had about 40 participants (age 14-19).


Events were animated by prof. J. Turnau from Cracow - IFJ

Some physics teachers took part.

3 staff from our Institute,3 PhD students 2 graduate students were involved, too.


Events took place at 2 different schools. Participants were from about 12 schools (most of them are involved in CR Project).


Events started at 10am and ended about 3pm with one 30 minutes break.

First part: ●introduction to high energy physics,●introduction to the studied problem in HoC event (how many basic particles are, relation to cosmology)●instruction to the animation program











Second part: ●Study of Z0 decays ●Summary of results and conclusions.



Second part: ●Study of Z0 decays ●Summary of results and conclusions.

PC like computers with MSWindows andMcIntosh with MSWindows - like systemwere used.

PC type computers with MSWindows are the most popular computers at schools in Poland.At lab we use Linux at PCs, and the HoC animation was not working correctly (might be that we have not used properly the software like plugins, applets etc.)











In March 2005 we plan in Lodz, Poland3 sessions correlated with other sessions in Europe.

Prof. Jacek Turnau (IFJ Cracow)and dr Grzegorz Wrochna (IPJ Warsaw)plan HoC Masterclass sessions in Cracow, Katowice and Warsaw.
