Tomography of LIP-Coimbra
A RPC based Muon Telescope has been operating in the LIP-Coimbra detector laboratory for many years. It is used to test each new detector plane that is produced there. We can use the data also to image the building of the UCoimbra Physics department building.
There is a lot of data available from the detector test muon telescope at Coimbra.
This is a 2.0 m x 0.5 m x 0.5 m telescope, with 4 planes at Z=(2.25,6.75;49.75,52.25)cm.
The new detector planes are at 143 cm for testing, and do not participate in the trigger.
- The data consists on (time, charge) x 2 ends x 15 strips x 4 RPC planes
- The trigger is a coincidence, within 50 ns, of 1(/2) top and 1(/2) bottom signals
- The event T0 is defined as the minimum of the times (T1) on the trigger side
- The two top planes are 4 gap RPCs, the two lower are 10 gaps RPCs, sharing HV
- Monitoring has 3 HV, 4 gas flux, 1 current + enviorment at test plane (8T, 1P, 1H)
Some pre-treated data is in: www.coimbra.lip.pt/~alberto/data.tar.gz with format:
- Ano, mes, dia, hora, minuto, segundo,
- Posição longitudinal P1, P2, P3, P4, - diferença de tempo, escala de TDC bins
- Posição transversal de P1, P2, P3, P4, - 1 de 15 strips de 30 mm (0.4 mm de intervalo)
- Tempos do P1, P2, P3, P4, sem calibrar - média dos tempos, usada no trigger
- Outras 128 variáveis de um plano testado a 143 cm, que não esta no trigger.
- A posição vertical é P1=49.75 cm, P2=52.25 cm, P3=2.25 cm, P4=6.75cm.
=> Good for practicing data cleaning, data reconstruction and imaging techniques
=> Good plans for master thesis, smaller student projects and cases for outreach
The master thesis of Vitor (USP-S.Carlos) is based on this data
