Update on the ANAIS experiment. ANAIS-0 prototype results at the new Canfranc Underground Laboratory
ANAIS experiment will look for dark matter annual modulation using NaI(Tl) scintillators at the Canfranc Underground Laboratory (LSC). Highly purified NaI(Tl) crystals are being developed to reach the required sensitivity. In a parallel way, the ANAIS-0 module (made with a low background St Gobain N...

| description | ANAIS experiment will look for dark matter annual modulation using NaI(Tl) scintillators at the Canfranc Underground Laboratory (LSC). Highly purified NaI(Tl) crystals are being developed to reach the required sensitivity. In a parallel way, the ANAIS-0 module (made with a low background St Gobain NaI(Tl) crystal) has been taking data at the LSC, testing different configurations: various photomultiplier tubes (PMTs) models with/without light guides. Low background PMTs with light guides and ultra low background PMTs without light guides have shown a similar contribution to the background. A complete simulation of the ANAIS-0 module with shielding in the different configurations tested has been carried out and compared with the experimental data, considering contributions to the background from NaI bulk contaminants, PMTs, light guides, quartz windows and shielding materials. A good understanding of the background above 500 keV can be reported. |
