11 Charged particle in electric and magnetic fields Magnetic rigidity: Bρ = mv q 2Tm q Electric rigidity: Resolving power: Eρ = pv q R = 2x 2T q ( x Δ) ( x x) 00 Deflection angles in electric field: α α ER p A A ER p q q ER p Universal: - Both electric and dipole fields are needed - Beam is dumped inside the first dipole (chamber) - Mass resolving power about 350 FWHM can be reached - Full energy beam suppression factor of can be expected
12 Mass separators all around the world: some trends DRS: Q1-Q2-Q3-WF1-WF2-Q4-Q5- Q6-S1-S2-MD1-Q7-Q8-Q9 (13.0 m) CARP: Q1-MD1-H1-H2-ED1-H3-Q2 CAMEL: Q1-Q2-ED1-S1-MD1-S2-ED2 HIRA: Q1-Q2-ED1-M1-MD1-ED2-Q3-Q4 (8.6 m) JAERI-RMS: Q1-Q2-ED1-MD1-ED2-Q3-Q4-O1 (9.4 m) FMA: Q1-Q2-ED1-MD1-ED2-Q3-Q4 (8.2 m) EMMA: Q1-Q2-ED1-MD1-ED2-Q3-Q4 (9.04 m) JYFL new: Q1-Q2-Q3-ED1-MD1 (6.74 m) Q S H M O WF ED MD quadrupole sextupole hexapole multipole octupole velocity filter electric dipole magnetic dipole
13 Design principles and aberrations - Maximizing angular, mass and energy acceptance while minimizing geometric and chromatic aberrations. - The largest aberrations are (x δ 2 ), (x θδ) and (x θ 2 ). These are minimizedbyaddinga curvatureto the magnetic dipole entrance and exit. - Higher order aberrations found to be negligible.
14 Optical layout in floor coordinates
15 Angular focus in x- and y-directions X-direction, 5 angles: 0, ±15 and ±30 mrad Y-direction, 5 angles: 0, ±20 and ±40 mrad
16 Energy focus and mass dispersion in x-direction Energy deviation: 0, ±3.5 and 7.0 % 3 different angles 3 different energies 3 different masses Angles: 0 and ±30 mrad, Masses: 0 and ±1 % Energies: 0 and 7.0 %
17 Main properties of the new separator compared to FMA FMA JYFL new - Configuration QQEDMDEDQQ QQQEDMD - Horizontal magnification Vertical magnification M/Q dispersion mm/% 8.1 mm/% - First order resolving power, mm beam spot -Solid angle acceptance 8 msr 10 msr - Energy acceptance for central mass and angle +20 % - 15 % +20 % - 15 % - M/Q acceptance ± 4 % ± 7 %
18 What kind of research work can be done were RITU separator is not feasible Probing the N Z line up to 112 Ba - decay spectroscopy (proton and α-particle decay) at the 100 Sn region - rp-process - proton-neutron pairing interaction - mirror nuclei o study of isospin symmetry breaking o proton skins (N < Z nuclei) D. Joss - superdeformation and hyperdeformation (N Z 40) Methods - focal plane detector system: o DSSSD, position sensitive gas counter (1 mm granularity) - Tracking o Ge-detectors -MWPC & IC o Z- identification - tape system - focal plane spectroscopy - α, proton, β, γ, β-delayed protons and alphas - prompt and delayed coincidences - in-beam spectroscopy tagging with using focal plane measurables
19 Phase space correction

21
22 Mass separation at focal plane
23 X-deviations versus TOF can be seen in phase space corrected data -> time correction can be made to improve x-resolution
24 Simulation of electric field in deflector (code Poisson Superfish) - gap 14 cm - rounded edges - splitted anode - maximum voltage between plates is about 0.5 MV
25
26 Simulating particle trajectories in deflector field Simple modified Euler equation is used to trace particles in electric field. Real transfer matrix coefficients can be obtained from these simulations. This more realistic matrix can be used in optical simulations of the new separator. 147 Tm: 222 MeV, 147 u, 37 e 100 MeV, 100 u, 26 e 92 Mo: 362 MeV, 92 u, 32 e 200 MeV, 50 u, 21 e
