What's new

AMS ¹⁴C dating in Poznañ started in mid-February 2002. Since that time, the number of samples dated per month was gradually increasing. Besides, we were continuously monitoring the quality of our dating.

Since December 2003 the ¹⁴C dating unit consists of Poznañ Radiocarbon Laboratory and AMS Laboratory. The new structure works as effectively as the former one, and the change does not alter the quality of our dating and the manner of our contact with the external customers.

In summer 2004, we extended our sample preparation lines. This expansion significantly increased our throughput and reduced our turnover time.

	On 15.10.2012 we made 50000th AMS measurement.
	On 14.04.2011 we made 40000th AMS measurement.
	In December 2009 we launched system for on-line sample registration
	The results of 3rd stage of VIRI, published in July 2009, confirm reliability of our dating
	Reorganisation (August 2009) enabled us to increase our throughput by up to 30%
	In June 2009 we had 4-weeks' break in operation of the accelerator
	In October 2007 we launched the program for persistent customers
	In June 2007 we commissioned NC analyser for screening of bone samples
	On 20.04.2007 we made 20000th AMS measurement.
	On 14.03.2005 we made 10000th AMS measurement.
	In October 2003, the first reparation of the accelerator was necessary.
	In September 2003 we significantly reduced the background of the AMS spectrometer.
	We can perform 14C dating of samples smaller than 1mgC

European projects

Our center participates in three European projects:

	Integrated Project: MILLENNIUM „European climate of the last millennium"
	Integrated Project: ECOCHANGE “Challenges in assessing and forecasting biodiversity and ecosystem changes in Europe"
	RTN NICE: „Network for Ice Sheet and Climate Evolution”

The official partner in these projects is the Adam Mickiewicz University, and the tasks of the projects are realized by ¹⁴C AMS Laboratory

Failures of the accelerator

January 2011


Wear on the pelletron chain and the chain drive wheels	Worn working surface of the chain drive wheel (after 14000 hours of work)	Fragment of the worn chain

June 2009


Failure of the pump in the accelerator tank	Rotor of the turbomolecular pump totally crashed on 14.06.2009 (after 7.5 yr of continuous work)	Parts of the rotor in the mini exhibition on spectacular failures of the components of our AMS spectrometer

October 2003

It was only a fan...	.. it costed 50 PLN and several days of work.

Our throughput

The graph below shows the number of ¹⁴C dates obtained since the beginning of our activity.

Keeping high throughput of our Laboratory, in the last months we distinctly decreased our turnover time (time between sample's arrival to Poznan and age reporting). Currently, this time is ca. 12-14 weeks.
