SVIRCO OBSERVATORY
During the 1st International Geophysics Year (1957) an international network of
“ground-based detectors” for continuous cosmic ray measurements was world-wide
established.
The cosmic ray station of Rome joined this network with the purpose to study the time
variations of primary cosmic rays (Studio Variazioni Intensità Raggi Cosmici: S.V.I.R.CO.)
and their modulation in the heliosphere.
From July 1957 to April 1997, the SVIRCO Station (now Observatory) performed
uninterrupted measurements at the Physics Department “G. Marconi” of “La Sapienza”
University of Rome (41.90° N, 12.52° E, altitude about 60 m a.s.l.)
In May 1997 the neutron monitor was moved into the Physics Department “E. Amaldi”
of “Roma Tre” University. Since then it has been continuously running at the new location
(41.86° N, 12.47° E, altitude about s.l.).
The SVIRCO Observatory (INAF/IIAPS-UNIRomaTre collaboration) is housed in a
reserved building provided with a double air-conditioning system. The room temperature is
maintained in a range of 23°-28° C, meanwhile the relative humidity is kept below 60%.
Either the ambient parameters are continuously checked and recorded by digital sensors.
Their time histories have been plotted in this report.
On January 1, 2005 three counters were added to the detector. After this upgrade,
from 17 to 20 NM-64, the SVIRCO neutron monitor is still composed by 5 sections, but the
arrangement varied as follow: three 3-counter, one 5-counter and one 6-counter units.
The enhancement improved not only the overall counting rate of 15.6 % (January
2005) but, as a result, also the statistical quality of the recorded data.
Each one of the 20 BF3 proportional counters (BP-28 type) is equipped with a smart
amplifier/discriminator circuit including a spectrum stabilizer. This new electronic unit,
developed in our laboratory, holds firmly the pulse height spectrum of the amplifier output
(within a range of more than 150 volts around the operating voltage), providing the counter
with an effective protection against high voltage variations.
Anyway, systematic and exhaustive tests of the counters are regularly performed.
The output pulses of the amplifiers, discriminated by the threshold gates, are collected and
stored into a multi-channel analyzer. The analysis of the height distribution (spectrum) of the
amplifier pulses coinciding with the discriminator ones, is essential to verify the long term
efficiency of each counter together with the amplifier gain and the discriminator threshold.
As well as the amplifier/discriminator circuits, a large part of the electronic
instrumentation operating in the Observatory was designed and realized in our laboratory
together with the software for data acquisition and pre-elaboration.
To minimize the risk of data loss and to improve the overall data reliability, two
independent systems perform the data acquisition at the same time. Each system is remotely
controlled by a dedicated computer and is timed by a high stability quartz clock and/or a GPS
receiver. One equipment (VXI) runs according to a timing of 1 minute and fulfils the
acquisition of each single counter. The other one (OLD) records the individual 5-minute
counting rate of each detector section in addition to the rates of the overall multiplicity, sorted
into separated counting channels (from 1 to greater than 8). The counting rates of the two
independent systems are checked each other on hourly base to detect possible
measurement errors. The annual time history of the difference between the counting rates of
the two systems is comprised in this paper.
A special care is applied to the atmospheric pressure measurements which are
carried out by three high-precision barometers. These instruments, achieving a resolution up
to 0.01 hPa, are continuously cross-checked for the best measuring accuracy and reliability.
Furthermore the barometers are equipped with different types of transducer namely: vibrating
cylinder, aneroid and quartz, therefore throughout their different behaviours, it is possible to
point out the occurrence of any long-term drift and eventually to re-calibrate the instruments.
The yearly check of the barometers is here reported.
More details of the complete acquisition system can be found on the included block
diagram.

The overall stability of the neutron monitor is controlled by means of the section
ratios. The hourly counting rate of each section, divided by the total rate, is plotted in real
time on a daily diagram. Moreover, the daily averages of these ratios are separately plotted,
as percentage, in monthly histograms. The annual series of histograms, included in this
report, shows the long term stability of each section.
In order to verify the coherence between the variations of the nucleonic intensity
recorded by SVIRCO-Rome and by another observatory with similar characteristics, a
comparative data analysis has been finally performed with the neutron monitor data of
Hermanus (South Africa - 34.42° S, 19.23° E, altitude 26 m a.s.l.). This Observatory was
chosen not only for its data availability, but also for its suitable geographic location. With a
cut-off energy (4.58 GV) and altitude (26 m a. s.l.) similar to Rome it is also far enough to
avoid correlation between the local pressure changes of the two monitors.
Both data sets have been normalized to their respective annual average and then
plotted, together with their ratio, on daily basis and also in a regression form.

DATA PRESENTATION
The intensity data, of the secondary nucleonic component of cosmic ray, detected in
Rome at the SVIRCO Observatory, were corrected for pressure variations at a reference
level of 1009.25 hPa with an attenuation coefficient of 0.70% / hPa.
a) Tables:
The hourly corrected data are reported in tabular form for each month together with
the daily ratios section Ri. The Ri ratios (%) are computed as the rate of each section
(channel i) divided by the total rate. Only n -1 section ratios are provided, being n the number
of sections.
The hourly and daily averages (in hPa) of the atmospheric pressure measured at the
Observatory, are also presented in monthly tables.
Furthermore, the monthly averages of the values, reported either in the correcteddata tables or in the pressure ones, are shown below them.
b) Graphs
The hourly-corrected data were also multiplied by a suitable normalization factor and
plotted in monthly graphs. The normalization was evaluated as percentage of the counting
rate average in the period from January to February 1997, when the Monitor operated at the
previous location of “La Sapienza” University. The reference counting rate level (100%),
computed for such a referential period, is equal to 554946 counts/hour. The set of
normalized graphs are provided for long-term analysis.
The monthly graphs of the atmospheric pressure are reported too.

MEASUREMENT INTERRUPTIONS
OCTOBER 13-14, 2011
On October 13 at 15.35 a total black-out occurred at the Physics Department because of a
failure in the main electrical cabinet. The fault was fixed on October 14 at around 17.10 hrs.
Thereby the neutron monitor was not operating in the above period.
DECEMBER 26, 2011 - JANUARY 2, 2012
During the period 27-31 December 2011 the planned renovation of the Physics Department
electrical system was performed. In order to prevent possible serious damages to
instrumentation a precautionary suspension of the Observatory activity was arranged. The
neutron monitor was switched off on December 26, 2011 at 12.05. It restarted operating on
January 2, 2012.
HOURLY RECOVERED DATA - YEAR 2011
