UCN optics, polarization foils and spinflipper for the munich nEDM approach Thorsten Lauer

2 Demands in UCN components T.Lauer – EDM workshop Oak Ridge Oct.2012 UCN guides UCN polarizer UCN detectors UCN storage cell UCN spin guiding

SR6 exit S-bend in UCN guide UCN source Biological shield Neutron life-time experiment Qbounce Reactor wall Halle Ost EDM Phase space transformer SC spin filter 3 28 m UCN beam positions at FRM-2 T.Lauer – EDM workshop Oak Ridge Oct.2012

UCN optics infront of the EDM SC magnet + spin flipper 4 T.Lauer – EDM workshop Oak Ridge Oct.2012 EDM spectrometer is at the same floor level as the source

Manipulating the UCN spectrum for nEDM: B 0 ≈ 1.5 T RF frequency ≈ 40 MHz to do: - building a spinflipper (birdcage resonator,…..?) - Ordering superconducting magnet (length min. 600 mm, warm bore of 300 mm) 5 T.Lauer – EDM workshop Oak Ridge Oct.2012

Inside the EDM UCN guides UCN switch Polarisation foil in front of the detector UCN bend sections 6 T.Lauer – EDM workshop Oak Ridge Oct.2012

UCN guides New sputtering facility for UCN guides: Coatings of NiMo,Cu, Ti, supermirrors… inside tubes - max. guide length 1.8 m - inner diameters from 50 to 150 mm 3.6m long vacuum chamber will arrive in October Transport system is ready 7 T.Lauer – EDM workshop Oak Ridge Oct.2012

UCN guides Transmission was measured to be 97.6% per meter (similar to replica!) 8 T.Lauer – EDM workshop Oak Ridge Oct.2012

UCN bend sections (1-3) NiMo coated glass bends (30 0,45 0 ) (4) Stainless steel 45 0 selfmade bend sections: 92% transmission 9 T.Lauer – EDM workshop Oak Ridge Oct.2012

UCN guides Supermirror with m = 1.5 (360 neV): 15 double layers of NiMo and Ti Bild V F = 360 neV measured 10 T.Lauer – EDM workshop Oak Ridge Oct.2012 What storage times can be expected? We will hopefully investigate this next year at ILL

UCN Switch Design for new switch will be similar (known technique) 11 T.Lauer – EDM workshop Oak Ridge Oct.2012

Development of UCN polarizers Bild große anlage - supermirrors - polarizers - further neutron optics - …. Sputtering facility for Planar substrates : Substrat size : 700 x 300 mm² 12 T.Lauer – EDM workshop Oak Ridge Oct magnetrons working in DC, RF or pulsed DC mode Coating homogeneity < 0.5%

Development of UCN polarizers Polarisation with single iron layers on Al - foils 96.0+/- 2.5% (magnetisation field 10mT!) 13 T.Lauer – EDM workshop Oak Ridge Oct.2012

Development of UCN polarizers 14 T.Lauer – EDM workshop Oak Ridge Oct.2012 Properties of the iron layer strongly depend on the production parameters Magnetisation field 10mT 150nm thick iron layer -> high transmission

A UCN superpolarizer 15 T.Lauer – EDM workshop Oak Ridge Oct /- 1.0% 10 double layers Fe/Si on Si-wafer or Al-foil

Spin Gymnastics 16 T.Lauer – EDM workshop Oak Ridge Oct.2012 SC & SF solenoid Cosine coil Mu-metal shield Cascade-U detector Spin transport system is under preperation Should be tested at beginning of 2013

Outlook Coating techniques and know-how exists UCN guides can be produced quite soon in new facility UCN polarizer foils can be produced Development of a UCN detector for simultaneous spin detection in collaboration with Heidelberg Design of a working UCN switch exists and will be adapted UCN-shutter and -spin transport design is on the way We have to take care about the storage cells 17 T.Lauer – EDM workshop Oak Ridge Oct.2012
