The ion optical properties of the Munich Q3D-spectrograph investigated by means of a special experimental ray tracing method

Production of26Al in stellar hydrogen-burning environments: Spectroscopic properties of states in27Si

“…A 25 MeV beam of 3 He 2+ ions (I ≈ 550 nA) was produced with an electron-cyclotron-resonance-like ion source [38] and an MP tandem accelerator. This beam was transported to the target position of a quadrupoledipole-dipole-dipole (Q3D) magnetic spectrograph with superior intrinsic energy resolution ∆E/E ≈ 2 × 10 -4 [39]. primarily to characterize background due to reactions on the carbon and oxygen present in the enriched silicon target, and the magnesium target was used to help calibrate the focalplane of the spectrograph.…”

Nuclear structure studies relevant to 136Xe ββ decay

“…For the measurements we collected triton and alpha particle spectra at laboratory scattering angles of 5 • -50 • and 5 • -45 • respectively, using the high resolution Q3D magnetic spectrometer [16]. The focal plane detector [17] of the spectrometer comprised of two proportional counters filled with isobutane gas at ∼ 500 mbar (to measure the partial energy loss of the ejectiles) and a 7 mm thick plastic scintillator to completely stop them.…”

High-resolution study of excited0+states in200Hg and202Hg

“…Within the last decade, much work has been done to investigate 0 + excitations in nuclei using the high-resolution Q3D magnetic spectrograph [1] at the Maier-Leibnitz Laboratory (MLL) Tandem accelerator in Munich. The Q3D spectrograph with its focal plane detector [2] has turned out to be a very powerful tool for the identification of 0 + states by measuring the characteristic forward peaking of L = 0 transfers (Ref.…”

“…The present paper completes the publication of all the existing data from the (p, t) campaign from Gd to Hg that was carried out using the ultra-high resolution instrument in Munich. [9] using an ultra-high resolution setup consisting of the Q3D magnetic spectrograph [1] and the high-resolution focal-plane detector described in Ref. [2], with typical triton energy resolution at 3-5 keV.…”
