Phy­si­ka­lisch-Tech­ni­sche Bun­des­an­stalt

The Physikalisch-Tech­nis­che Bundes­an­stalt (PTB) is the national met­ro­logy insti­tute of the Fed­eral Repub­lic of Ger­many. Its man­date is to provide sci­entific and tech­nical ser­vices and to pro­mote pro­gress and reli­ab­il­ity in met­ro­logy for the bene­fit of soci­ety, the eco­nomy and sci­ence.

At our Ber­lin-Char­lot­ten­burg site, Depart­ment 8.2 (Biosig­nals) is seek­ing a can­did­ate to fill the fol­low­ing pos­i­tion as soon as pos­sible for a fixed term of three years:

Postdoc­toral researcher or doc­toral can­did­ate spe­cial­iz­ing in atomic phys­ics or a com­par­able sub­ject

Up to Remu­ner­a­tion Group 14 TVöD Bund ○ Full-time (39 hours/week) ○ Fixed-term con­tract

For doc­toral can­did­ates, the remu­ner­a­tion will be paid in accord­ance with Remu­ner­a­tion Group 13 TVöD Bund (85 %).

Working field:

The pre­cise real­iz­a­tion and dis­sem­in­a­tion of the units is one of the core tasks of PTB. In a joint pro­ject with Depart­ment 2.5 (Semi­con­ductor Phys­ics and Mag­net­ism) at PTB Braun­sch­weig, the unit of mag­netic flux dens­ity, the tesla, is to be determ­ined more accur­ately and on a sig­ni­fic­antly broader field range com­pared to the pre­vi­ous method. For this pur­pose, the pro­ton NMR method has to be replaced with meas­ure­ments on hyper­pol­ar­ized 3He. At our site in Ber­lin, the focus will ini­tially be on the ultra-low field range (< 10 µT). For this purpose, the 3He hyperpolarization method (MEOP) needs to be adapted to the specific demands of measurements in the magnetically shielded room BMSR-2 in Berlin. Subsequently, an extension to the high field range (> 1 T) is envis­aged.

Your tasks will include:

  • Devel­op­ing and installing a 3He MEOP setup which is suit­able for applic­a­tion in the BMSR-2
  • Inde­pend­ently car­ry­ing out meas­ure­ment cam­paigns in the BMSR-2 in close coordin­a­tion with the col­leagues in Braun­sch­weig
  • Determ­in­ing the stat­ist­ical and sys­tem­atic meas­ure­ment uncer­tain­ties
  • Car­ry­ing out joint meas­ure­ment cam­paigns at PTB's site in Braun­sch­weig
  • Com­par­ing the res­ults with pre­vi­ous meas­ure­ment meth­ods and elab­or­at­ing fur­ther improve­ment con­cepts (poten­tially based on com­pletely new meas­ure­ment meth­ods, hyper­pol­ar­ized 1H, alkali mag­ne­to­meter)
  • Present­ing and pub­lish­ing our res­ults


  • You have com­pleted your uni­versity stud­ies in phys­ics or a com­par­able field (mas­ter’s degree or Ger­man Dip­lom) (if you are a postdoc­toral researcher, you have obtained a doc­tor­ate in a sci­entific sub­ject).
  • You have exper­i­ence in NMR meth­ods, in meas­ure­ment meth­ods in ultra-low mag­netic fields (SQUIDs, OPMs, flux gates) and their inter­pret­a­tion as well as with laser-based spin polar­iz­a­tion tech­niques.
  • You have prac­tical exper­i­ence with exper­i­mental setups and data acquis­i­tion as well as pro­gram­ming for the pur­poses of data ana­lysis.
  • You are a strong team player with excel­lent com­mu­nic­a­tion skills.
  • You have a good com­mand of Ger­man and Eng­lish, both spoken and writ­ten.
  • You are will­ing to travel within Ger­many and abroad within the scope of your assign­ment.

What we offer:

  • The oppor­tun­ity to work at one of the world’s lead­ing research insti­tu­tions and take advant­age of its out­stand­ing sci­entific infra­struc­ture
  • Intens­ive super­vi­sion of your doc­tor­ate in an inter­dis­cip­lin­ary team
  • Remu­ner­a­tion in accord­ance with Ger­many’s col­lect­ive agree­ment for fed­eral-level pub­lic ser­vice employ­ees (Tari­fver­trag öffent­licher Dienst Bund – TVöD)
  • Vari­ous work­place health and well­ness options
  • Excel­lent pub­lic trans­port­a­tion con­nec­tions and a sub­sidy towards the cost of your pub­lic trans­port ticket for the VBB (VBB-Firmenticket)
  • Free park­ing for cars, motor­bikes and bicycles
