職位描述：

　　馬克斯普朗克物理研究所邀請(qǐng)申請(qǐng)人參加

　　博士后職位

　　專注于與未來大規(guī)模中微子雙β衰變（0νββ）實(shí)驗(yàn)和GERDA II期數(shù)據(jù)分析相關(guān)的研發(fā)。這個(gè)開放是校準(zhǔn)研究中心CRC 1258“天體和粒子物理中的中微子和暗物質(zhì)”的一部分。

　　基于鍺的0ββ衰變實(shí)驗(yàn)被設(shè)計(jì)用于研究中微子的性質(zhì)并通過搜索76Ge的0νββ衰變來測(cè)試輕子數(shù)量守恒。目標(biāo)是要么建立Lepton數(shù)量違反和中微子的Majorana性質(zhì)，要么將相關(guān)的排除限制推到中微子振蕩指示的中微子質(zhì)量尺度。

　　對(duì)于基于噸規(guī)模的鍺基0νββ衰變實(shí)驗(yàn)而言，相對(duì)于GERDA實(shí)驗(yàn)來說，進(jìn)一步降低輻射背景是必不可少的，GERDA實(shí)驗(yàn)是該領(lǐng)域目前世界領(lǐng)先的實(shí)驗(yàn)。閃爍聚合物PEN可以在LEGEND實(shí)驗(yàn)的第一階段中用作自我否定的結(jié)構(gòu)材料。使用這種材料可以顯著提高背景識(shí)別效率，從而提高對(duì)0βββ衰變的敏感性。

　　預(yù)計(jì)成功的候選人將在新材料的開發(fā)中發(fā)揮主導(dǎo)作用，并應(yīng)推動(dòng)將鍺探測(cè)器整合到由自動(dòng)消除聚合物制成的環(huán)境中。預(yù)計(jì)候選人將積極參加“兒童權(quán)利公約”的聯(lián)合活動(dòng)。

　　該職位的正式要求是實(shí)驗(yàn)物理學(xué)博士。

　　候選人應(yīng)具有（astro-）粒子物理或探測(cè)器物理學(xué)的背景。在聚合物研究，低背景物理和HPGe二極管方面的經(jīng)驗(yàn)，以及使用C ++，Root和GEANT 4編程的豐富知識(shí)是一個(gè)優(yōu)勢(shì)。

　　薪酬和福利與公共服務(wù)機(jī)構(gòu)（TVöDBund）相稱。合同最初限于2年。馬克斯普朗克協(xié)會(huì)是一個(gè)機(jī)會(huì)均等的雇主。目標(biāo)是提高婦女在其代表性不足的比例。因此，特別鼓勵(lì)婦女申請(qǐng)。該協(xié)會(huì)致力于雇用更多有特殊需求的人。有特殊需要的人的申請(qǐng)?zhí)貏e受歡迎。

　　The Max Planck Institute for Physics invites applications for a

　　Postdoctoral position

　　focused on R&D in connection with the future large scale neutrinoless double-beta decay (0νββ) experiment and analysis on GERDA phase II data. This opening is part of the Col-laborative Research Center CRC 1258 „Neutrinos and dark matter in astro and particle physics”.

　　Germanium based 0νββ decay experiments are designed to investigate the nature of the neutrino and to test Lepton number conservation by searching for 0νββ decay of 76Ge. The goal is to either establish Lepton number violation and the Majorana nature of the neutrino or to push the relevant exclusion limits to the neutrino mass scale indicated by neutrino oscillations.

　　For a ton scale germanium based 0νββ decay experiment it is indispensable to further reduce the background from radiation with respect to the GERDA experiment, the cur-rently world leading experiment in this field. The scintillating polymer, PEN, could be used as self-vetoed structural material already in the first phase of LEGEND experiment. Use of this material could lead to a significant improvement of background recognition effi-ciency and hence sensitivity for 0νββ decay.

　　The successful candidate is expected to take over a leading role in the development of the new material and should push forward the integration of germanium detectors into surroundings made from self-vetoed polymers. The candidate is expected to actively participate in joint activities of the CRC.

　　Formal requirements for this position are a PhD in experimental physics.

　　The candidate should have a background in (astro-)particle physics or detector physics. Experience in polymer research, low background physics and with HPGe diodes, and a good knowledge in programming with C++, Root and GEANT 4 are an advantage.

　　Salary and benefits are commensurate with public service organizations (TVöD Bund). The contract is initially limited to 2 years. The Max Planck Society is an equal opportunity employer. The goal is to enhance the percentage of women where they are underrepre-sented. Women, therefore, are especially encouraged to apply. The Society is committed to employing more people with special needs. Applications of people with special needs are particularly welcome.

　　Further information can be obtained from Dr. Béla Majorovits (bela@mppmu.mpg.de). Interested applicants should send an application letter including curriculum vitae, a statement of research interests, a list of main publications and arrange for three letters of support. Please send your complete written application by to ina@mpp.mpg.de.

　　The Max Planck Institute for Physics collects and stores personal data that you send for your application. Further information on the data collected can be found at https://www.mpp.mpg.de/en/studying-and-working/jobs/data-protection-statement-for-job-applications/
